Dear Shareholder:

   
         You are cordially invited to attend the Annual Meeting of Shareholders
of East Ridge Bancshares, Inc. ("East Ridge"), which will be held on Thursday
August 21, 1997, at 4154 Ringgold Road, Chattanooga, Tennessee 37412 at 7:00 
p.m., Eastern Daylight Savings Time (the "East Ridge Meeting").
    

         At this meeting, you will be asked to consider and vote upon a
proposed merger (the "Merger") involving East Ridge, The Bank of East Ridge,
the wholly-owned subsidiary of East Ridge ("Bank of East Ridge"), and
Cornerstone Community Bank ("Cornerstone"), pursuant to which Cornerstone will
be merged with and into Bank of East Ridge.  Upon the Merger, Bank of East
Ridge,  as a wholly-owned subsidiary of East Ridge, will be the surviving
company and will change its name to "Cornerstone Community Bank," and East
Ridge will amend its charter and change its name to "Cornerstone Bancshares,
Inc." ("New Cornerstone").  Shareholders of East Ridge may elect to receive
cash and/or newly issued shares of common stock of New Cornerstone ("New
Cornerstone Common Stock").   The proposed Merger is more fully described in
the accompanying Joint Proxy Statement/Prospectus.

         The Merger Agreement provides that shareholders of East Ridge who do
not exercise dissenters' rights  may elect to receive New Cornerstone Common
Stock and/or cash for their shares of East Ridge common stock.  The number of
shares of New Cornerstone Common Stock received in exchange for East Ridge
Common Stock will be based on an exchange ratio determined by multiplying the
number of shares of East Ridge Common Stock to be exchanged by $56.1772 and
then dividing by $12 (the "ERB Exchange Ratio").  Shareholders of East Ridge
who exchange their shares for cash will receive $56.1772 per share. 
Accordingly, each share of East Ridge Common Stock will be converted into the
right to receive 4.6814 shares of New Cornerstone Common Stock.  However, the
aggregate amount of cash to be delivered to the shareholders of East Ridge will
not exceed $4,287,500.  To the extent shareholders of East Ridge elect to
receive in the aggregate more than $4,287,500, cash will be paid on a pro-rata
basis to those East Ridge shareholders electing to receive cash. With respect
to New Cornerstone Common Stock received in the transaction by East Ridge
shareholders, the Merger Agreement provides for a tax-free exchange.

         The Merger Agreement provides that shareholders of Cornerstone who do
not exercise dissenters' rights will exchange each share of Cornerstone common
stock and each warrant currently held for one share of New Cornerstone Common
Stock and one warrant to purchase one share of New Cornerstone Common Stock for
$12 per share if exercised by February 8, 1998 and for $15 per share if
exercised by February 8, 2001 (the "Cornerstone Exchange Ratio").

         The Merger will result in a change of control of the ownership and
management of East Ridge.  Upon completion of the Merger, Cornerstone
shareholders will own a minimum of 79.4% of the outstanding shares of New
Cornerstone Common Stock and the officers and directors of Cornerstone will
continue as the officers and directors of New Cornerstone.

         The Board of Directors of East Ridge believes that the transactions
contemplated by the Agreement and Plan of Merger are fair to and in the best
interests of East Ridge and its shareholders.  The Boards of Directors of both
East Ridge and Cornerstone have approved the Agreement and Plan of Merger and
the Board of Directors of East Ridge recommends that you vote FOR approval of
the Agreement and Plan of Merger.  All shareholders are invited to attend the
East Ridge Meeting in person.  Approval of the Merger requires the affirmative
vote of a majority of the outstanding shares of common stock of East Ridge.
David E. Young, a director of East Ridge and Chairman of the Board of Bank of
East Ridge, beneficially owns 76,139 shares of East Ridge Common Stock, or
approximately 69.8% of the outstanding East Ridge Common Stock. Mr. Young has
agreed to vote all of his shares in favor of the Merger.  Accordingly, approval
of the Merger Agreement by the East Ridge shareholders is assured.

         At the East Ridge Meeting shareholders of East Ridge will also elect
six directors to serve as members of the Board of Directors of East Ridge until
the next annual meeting or until their successors are duly elected and
qualified.


         The enclosed Notice of Annual Meeting of Shareholders and Joint Proxy
Statement/Prospectus explain the Merger and provide specific information
relative to the East Ridge Meeting.  Please carefully read these materials and
thoughtfully consider the information contained in them.

         In order that your shares may be represented at the East Ridge
Meeting, you are urged promptly to complete, sign, date and return the
accompanying Proxy in the enclosed envelope, whether or not you plan to attend
the East  Ridge Meeting.  If you attend the

         East Ridge Meeting in person, you may, if you wish, vote personally on
         all matters brought before the East Ridge Meeting even if you have
         previously returned your Proxy.


                                                   Sincerely,

Statement/Prospectus explain the Merger and provide specific information

Meeting, you are urged promptly to complete, sign, date and return the
accompanying Proxy in the enclosed envelope, whether or not you plan to attend

                          EAST RIDGE BANCSHARES, INC.
         PROSPECTUS FOR 1,100,547 SHARES OF COMMON STOCK AND WARRANTS
                  TO PURCHASE 590,130 SHARES OF COMMON STOCK

   
         This Joint Proxy Statement/Prospectus and the accompanying forms of
proxy are being furnished in connection with the solicitation of proxies by the
Boards of Directors of East Ridge Bancshares, Inc. ("East Ridge") and
Cornerstone Community Bank ("Cornerstone") to be used at the Annual Meeting of
Shareholders of East Ridge to be held on August 21, 1997 at 7:00 p.m., Eastern
Daylight Savings Time (the "East Ridge Meeting") and the Annual Meeting of
Shareholders of Cornerstone to be held on August 21, 1997 at 7:00 p.m., Eastern
Daylight Savings Time (the "Cornerstone Meeting", and together with the East
Ridge  Meeting, the "Meetings"), in each case, at the main office of each in 
Chattanooga, Tennessee.  This Joint Proxy Statement/Prospectus and the 
accompanying forms of proxy are first being mailed to shareholders of East
Ridge and Cornerstone on or about August 5, 1997.
    

         At the Meetings,  shareholders of each of East Ridge and Cornerstone
will  consider and vote upon the approval and adoption of an Agreement and Plan
of Merger dated as of March 18, 1997 (the "Merger Agreement") among East Ridge,
The Bank of East Ridge ("Bank of East Ridge"), Cornerstone and David E. Young,
individually, a copy of which is set forth as Appendix A to the attached Joint
Proxy Statement/Prospectus.  The Merger Agreement provides for, among other
things, the merger of Cornerstone with and into Bank of East Ridge, a Tennessee
banking corporation that is a wholly-owned subsidiary of East Ridge (the
"Merger"), with Bank of East Ridge to be the surviving corporation in the
Merger, but which, upon the effectiveness of the Merger, will amend its charter
and change its name to "Cornerstone Community Bank."  Upon the effectiveness of
the Merger, East Ridge will amend its charter and change its name to
"Cornerstone Bancshares, Inc." ("New Cornerstone").  The Merger will result in a
change of control of the ownership and management of East Ridge.  Upon
completion of the Merger, Cornerstone shareholders will own a minimum of 79.4%
of the outstanding shares of common stock of New Cornerstone ("New Cornerstone
Common Stock") and the officers and directors of Cornerstone will continue as
the officers and directors of Cornerstone.

         Upon the effectiveness of the Merger (the "Effective Time"), each
share of East Ridge common stock ("East Ridge Common Stock") outstanding prior
to the Effective Time will be converted into a right to receive cash and/or New
Cornerstone Common Stock.  Shareholders of East Ridge who do not exercise
dissenters' rights may elect to receive New Cornerstone Common Stock and/or
cash for their shares of East Ridge common stock.  The number of shares of New
Cornerstone Common Stock received in exchange for East Ridge Common Stock will
be based on an exchange ratio determined by multiplying the number of shares of
East Ridge Common Stock to be exchanged by $56.1772 and then dividing by $12.00
(the "ERB Exchange Ratio").  Shareholders of East Ridge who exchange their
shares for cash will receive $56.1772 per share.  Accordingly, each share of
East Ridge Common Stock will be converted into the right to receive 4.6814
shares of New Cornerstone Common Stock.  However, the aggregate amount of cash
to be delivered to the shareholders of East Ridge will not exceed $4,287,500. 
To the extent shareholders of East Ridge elect to receive in the aggregate more
than $4,287,500, cash will be paid on a pro-rata basis to those East Ridge
shareholders electing to receive cash.   See "The Merger Agreement."

         At the Effective Time, each share of Cornerstone common stock and each
warrant exercisable for Cornerstone common stock (unless the context requires
otherwise, the Cornerstone common stock and warrants are referred to
hereinafter collectively as "Cornerstone Common Stock") outstanding prior to
the Effective Time will be converted into a right to receive one share of New
Cornerstone Common Stock and a warrant to purchase one share of New Cornerstone
Common Stock for $12 per share if exercised by February 8, 1998 and for $15 per
share if exercised by February 8, 2001 ("New Cornerstone Warrant").

         SEE "RISK FACTORS" ON PAGE 11 FOR A SUMMARY OF CERTAIN MATERIAL RISKS
AND CONSIDERATIONS RELATING TO AN INVESTMENT IN THE NEW CORNERSTONE COMMON
STOCK.

         This Joint Proxy Statement/Prospectus also serves as a Prospectus under
the Securities Act of 1933, as amended (the "Securities Act"), relating to a
maximum of 1,100,547 shares of New Cornerstone Common Stock and New Cornerstone
Warrants exercisable for the purchase of up to 590,130 shares of New Cornerstone
Common Stock issuable in the Merger.  Upon completion of the Merger, Cornerstone
shareholders will own a minimum of 79.4% of the New Cornerstone Common Stock.

         There is no established trading market for either the East Ridge
Common Stock or the Cornerstone Common Stock.  To management of East Ridge's
knowledge and management of Cornerstone's knowledge, the most recent
transactions with respect to the East Ridge Common Stock and the Cornerstone
Common Stock were $56.17 and $13.50, respectively.   There will be no trading
market for the New Cornerstone Common Stock and New Cornerstone Warrants upon
their issuance.

         At the Meetings, the shareholders of each of East Ridge and
Cornerstone also will be asked to elect nominees to serve on their respective
boards of directors until their respective successors are elected and
qualified.  Additionally, shareholders of Cornerstone will be asked to approve
the amendment of its Charter to authorize the exercise of trust powers and to
ratify the appointment of auditors.

1986, as amended (the "Code"), for holders of Cornerstone Common Stock and for
holders of East Ridge Common Stock to the extent of the stock consideration
received by the East Ridge shareholders and the Cornerstone shareholders in the
Merger. However, the exchange by the Cornerstone shareholders of Cornerstone
warrants for New Cornerstone Warrants may be a taxable transaction.

charter and change its name to "Cornerstone Bancshares, Inc." Approval of the
Merger Agreement requires the affirmative vote of a majority of the outstanding
shares of East Ridge.

         At the East Ridge Meeting, shareholders will also elect six directors
to serve as members of the East Ridge Board of Directors until their successors
are elected and qualified.   The election of each of the nominees requires the

Ridge, beneficially owns 76,139 shares of East Ridge Common Stock, or
approximately 69.8% of the outstanding East Ridge Common Stock. Mr.Young has
agreed to vote all of his shares in favor of the Merger.  Accordingly, approval
of the Merger Agreement by the East Ridge shareholders is assured.

   
         The Cornerstone Meeting.  The Cornerstone Meeting will be held on
Thursday, August 21, 1997, at 5319 Highway 153 Chattanooga, Tennessee 37343 at

Cornerstone Common Stock at the close of business on July 27, 1997 (the
"Cornerstone Record Date") will be entitled to vote at the Cornerstone Meeting. 
On the Cornerstone Record Date, there were issued and outstanding approximately
590,130 shares of Cornerstone Common Stock held by approximately 400 holders of
record.  Each share is entitled to one vote on each matter to come up at the
Cornerstone Meeting.
    

         At the Cornerstone Meeting, shareholders of Cornerstone will be asked
to consider and vote upon a proposal to approve and adopt the Merger Agreement,
which provides for the merger of Cornerstone with and into Bank of East Ridge
with Bank of East Ridge being the surviving banking corporation and amending
its charter and changing its name to "Cornerstone Community Bank."  Upon
consummation of the Merger, East Ridge will amend its charter and change its
name to "Cornerstone Bancshares, Inc."  The Merger will result in a change of
control of the ownership and management of East Ridge.  Upon completion of the
Merger, Cornerstone shareholders will own a minimum of 79.4% of the
outstanding shares of New Cornerstone Common Stock and the officers and
directors of Cornerstone will continue as the officers and directors of

the Cornerstone Charter to authorize the exercise of trust powers and (iii)
ratify the appointment of auditors.  The election of each of the nominees
requires the affirmative vote of the holders of a plurality of the votes cast
at the Cornerstone Meeting.  The approval of the amendment to the Cornerstone
Charter requires the affirmative vote of a majority of the outstanding shares
of Cornerstone Common Stock,  and the appontment of auditors requires that the
votes cast in favor of the proposals exceed the votes against the proposals.

        As of the Cornerstone Record Date, directors and executive officers of
Cornerstone owned beneficially on aggregate of 241,822 shares of Cornerstone
Common Stock, or approximately 41% of the shares of Cornerstone Common Stock
outstanding on such date.

TERMS OF THE MERGER

        Merger Consideration Available to East Ridge Shareholders.  Upon the 
effectiveness of the Merger (the "Effective Time"), each share of East Ridge
common stock ("East Ridge Common Stock") outstanding prior to the Effective
Time will be converted into a right to receive cash and/or New Cornerstone
Common Stock.  Shareholders of East Ridge who do not exercise dissenters'
rights may elect to receive New Cornerstone Common Stock and/or cash for their
shares of East Ridge common stock.  The number of shares of New Cornerstone
Common Stock received in exchange for East Ridge Common Stock will be based on
an exchange ratio determined by multiplying the number of shares of East Ridge
Common Stock to be exchanged by $56.1772 and then dividing by $12.00 (the "ERB
Exchange Ratio").  Shareholders of East Ridge who exchange their shares for
cash will receive $56.1772 per share.  Accordingly, each share of East Ridge
Common Stock will be converted into the right to receive 4.6814 shares of New
Cornerstone Common Stock.  However, the aggregate amount of cash to be
delivered to the shareholders of East Ridge will not exceed $4,287,500.  To the
extent shareholders of East Ridge elect to receive in the aggregate more than
$4,287,500, cash will be paid on a pro-rata basis to those East Ridge
shareholders electing to receive cash.  

         Although the Merger Agreement provides that in the event shareholders
of East Ridge elect less than $2,900,000 in cash, Cornerstone may terminate
the Merger Agreement, such eventuality is not likely to occur in that David E.
Young, who beneficially owns 76,139 shares of East Ridge Common Stock, or
approximately 69.8% of the outstanding shares of East Ridge has notified
Cornerstone that he intends to exchange up to 70% of the shares of East Ridge
Common Stock he owns for cash in the aggregate amount of $2,994,076.  However,
in the event the elections of the East Ridge shareholders, including Mr. Young,
for cash exceed $4,287,500.  Mr. Young's election will be pro rated equally
with all other East Ridge shareholders who have elected cash.  See "The Merger
- -- Terms of the Merger".


         The Merger will result in a change in control of the ownership and 
management of East Ridge.  Upon completion of the Merger, if all of the East
Ridge shareholders except Mr. Young who has agreed to exchange a certain        
portion of his shares for cash, elect to receive all of the remaining
approximately 153,975 shares of New Cornerstone Common Stock issuable in the
Merger, shareholders of East Ridge will own a maximum of 20.6% of the
outstanding shares of New Cornerstone Common Stock and Cornerstone shareholders
will own 79.4% of the outstanding shares of New Cornerstone Common Stock.  The
officers and directors of Cornerstone will continue as the officers and
directors of New Cornerstone.

         Merger Consideration Available to Cornerstone Shareholders. At the 
Effective Time, each share of Cornerstone common stock and each warrant
exercisable for Cornerstone common stock (unless the context requires
otherwise, the Cornerstone common stock and warrants are referred to
hereinafter collectively  as "Cornerstone Common Stock") outstanding prior to
the Effective Time will be converted into a right to receive one share of New
Cornerstone Common Stock and a warrant to purchase one share of New Cornerstone
Common Stock for $12 per share if exercised by February 8, 1998 and for $15 per
share if exercised by February 8, 2001 (unless the context requires otherwise,
"New Cornerstone Common Stock" includes the warrants exercisable for New
Cornerstone Common Stock).  New Cornerstone Warrants exercisable for the
purchase of up to 590,130 shares of New Cornerstone Common Stock are issuable
in the Merger.  See "The Merger -- Terms of the Merger."

         Fractional Shares.  No fractional shares of New Cornerstone Common 
Stock will be issued in connection with the Merger.  In lieu of fractional
shares, New Cornerstone will make a cash payment equal to the fractional
interest which an East Ridge shareholder would otherwise receive multiplied by
$56.1772.  The fractional interest will be determined by combining all shares
owned by such East Ridge shareholder.   See "The Merger -- Terms of the
Merger."

Election of Form of Merger Consideration

        As promptly as practicable after the Merger, New Cornerstone will
provide letters of transmittal to shareholders of East Ridge for the purpose of
exchanging their certificates of East Ridge Common Stock for New Cornerstone
Common Stock and/or cash as elected by the shareholder.  To the extent
shareholders of East Ridge elect to receive New Cornerstone Common Stock, such
election will be satisfied.  The amount of cash received by an East Ridge
shareholder is subject to the availability of cash to the extent shareholders
of East Ridge elect more than $4,287,500 in cash.  In such event, the amount of
cash up to the maximum amount of $4,287,500 will be prorated among all
shareholders of East Ridge, including Mr. Young, requesting cash.  In the event
all of the shareholders of East Ridge elect to receive cash for all of their
shares of East Ridge, each shareholder would receive 70% of his Merger
consideration in cash and 30% in New Cornerstone Common Stock.

        As promptly as practicable after the Merger, New Cornerstone will
provide letters of transmittal to shareholders of Cornerstone for the purpose
of exchanging their certificates of Cornerstone Common Stock and their warrants
for certificates representing New Cornerstone Common Stock and New Cornerstone
Warrants.  See "The Merger -- Surrender of Certificates."

Advantages and Disadvantages of Form of Merger Consideration

        To the extent shareholders of East Ridge elect to receive New 
Cornerstone Common Stock, they will not recognize gain or loss upon the receipt
of New Cornerstone  Common Stock, except to the extent of any cash received in
lieu of fractional shares.  To the extent shareholders of East Ridge elect to
receive cash, they will recognize gain or loss as a result of the Merger.  See
"The Merger -- Certain Federal Income Tax Consequences."

        Additionally, there is no market for the New Cornerstone Common Stock
and there is no assurance that an active and liquid market will develop. 
Therefore, East Ridge shareholders who elect to receive New Cornerstone Common
Stock and who desire to liquidate their investment may be unable to do so.  See
"Risk Factors."

EFFECTIVE TIME

         The Effective Time of the Merger will be 5:01 p.m., Eastern time, on
the later to occur of the acceptance for filing by the Secretary of State of
the State of Tennessee of articles of merger filed in accordance with the
Tennessee Banking Act (the "TBA"), or on such later date as the articles of
merger may specify.  Unless otherwise mutually agreed upon by East Ridge and
Cornerstone, the Merger will occur on the last business day of the month after
all conditions contained in the Merger Agreement have been satisfied or waived,
including receipt of all regulatory approvals and termination of all statutory
waiting periods.

REASONS FOR THE MERGER; RECOMMENDATION OF BOARDS OF DIRECTORS

   
         The Board of Directors of East Ridge (the "East Ridge Board")
believes the Merger is fair to and in the best interest of East Ridge and its
unaffiliated shareholders and recommends that East Ridge's shareholders vote
FOR approval of the Merger Agreement despite the fact that David E. Young, the
principal shareholder of East Ridge, negotiated the transaction and negotiated
favorable terms for himself, including a consulting arrangement and the right
to require New Cornerstone to redeem shares of New Cornerstone Common Stock
which he receives in the Merger, that do not apply to unaffiliated East Ridge
shareholders.  See "The Merger -- Background of and Reasons for the Merger." 
For information on the interests of certain officers and directors of East
Ridge, including Mr. Young, in the Merger, see "The Merger -- Interests of
Certain Persons in the Merger."
    

         The Board of Directors of Cornerstone (the "Cornerstone Board")
believes the Merger is fair to and in the best interest of Cornerstone and its
shareholders and recommends that Cornerstone's shareholders vote FOR approval
of the Merger Agreement.  See "The Merger -- Background of and Reasons for the
Merger."  For information on the interests of certain officers and directors of
Cornerstone in the Merger, see "The Merger -- Interests of Certain Persons in
the Merger."

OPINION OF FINANCIAL ADVISER

         Mercer Capital ("Mercer") has delivered its written opinion to the
Cornerstone Board to the effect that, as of the date of the Merger Agreement
and the date of this Joint Proxy Statement/Prospectus, the transaction is fair,
from a financial point of view, to the holders of Cornerstone Common Stock.  A
copy of the opinion of Mercer dated April 25, 1997 is attached hereto as
Appendix B.  The opinion should be read in its entirety for a description of
the procedures followed, assumptions and qualifications made, matters
considered, and the limitations observed by Mercer. See "The Merger -- Opinion
of Cornerstone's Financial Adviser."

         The East Ridge Board determined that it was not necessary to engage a
financial advisor for the purpose of providing an opinion with respect to the
fairness of the transaction from a financial point of view to the holders of
East Ridge Common Stock.  The East Ridge Board made such determination based on
the facts that the East Ridge Board had previously retained Alex Sheshunoff &
Company as its financial advisor which had not been able to obtain any 
acquisition proposal superior to the Cornerstone proposal and management of
East Ridge had conducted, or caused to be conducted, a due diligence
investigation of the quality of the Cornerstone loan and securities
portfolios.  See "The Merger -- Background and Reasons for the Merger."
 
CONDITIONS; REGULATORY APPROVALS

         Consummation of the Merger is subject to various conditions, including
receipt of the shareholder approval solicited hereby, receipt of the necessary
regulatory approvals, receipt of an opinion of counsel regarding certain tax
aspects of the Merger, implementation, to the extent consistent with generally
accepted accounting principles ("GAAP"), of certain adjustments to East Ridge's
loan, litigation and real estate valuation policies and practices (including
loan classifications and levels of reserves) and satisfaction of customary
closing conditions.

         The regulatory approvals and consents necessary to consummate the
transactions contemplated by the Merger Agreement include the approval of the
Federal Deposit Insurance Corporation ("FDIC") and the Tennessee Department of
Financial Institutions (the "TDFI").  Applications have been submitted for such
approvals.  There can be no assurances as to when, if or with what conditions
such approvals will be granted.  See "The Merger -- Conditions to Consummation
of the Merger," "-- Regulatory Approvals" and "-- Conduct of Business Pending
the Merger."

TERMINATION OF THE MERGER AGREEMENT

         The Merger Agreement may be terminated at any time prior to the
Merger by the mutual consent of East Ridge and Cornerstone, in the event the
shareholders of either East Ridge or Cornerstone fail to approve the Merger
Agreement or by either if its Board of Directors so determines by a vote of the
majority of the members of its entire Board, in the event of a material breach
of a representation, warranty or covenant in the event such breach is not cured
within 60 days of notice of such breach is provided to the breaching party and
in the event East Ridge shareholders elect to receive consideration of less
than $2,900,000 in cash.  It is unlikely that the Merger Agreement would be
terminated for the last reason listed because David E. Young has agreed to
exchange 70% of his East Ridge Common Stock for cash in the aggregate amount of
$2,994,076.  See "The Merger -- Waiver and Amendment; Termination."

MANAGEMENT AFTER THE MERGER

         After the Merger, the directors and officers of Cornerstone
will become the directors and officers of East Ridge and Bank of East Ridge.
See "The Merger -- Management After the Merger."

INTERESTS OF CERTAIN PERSONS IN THE MERGER

         Certain members of East Ridge's management and the East Ridge Board
have certain interests in the Merger that are in addition to their interests as
shareholders of East Ridge generally.  Each of David E. Young, James D.
Renegar, James R. Young, Jr. and Daniel O. Crye is a party to a
Change-in-Control Protective Agreement and an Executive Salary Continuation
Agreement which provides for certain payments in the event their employment is
terminated under certain circumstances after a change in control of East Ridge.

         At the time of the Merger, David E. Young will waive his right to
receive severance payments pursuant to the Change-in-Control Protective
Agreement and will enter into a consulting agreement with East Ridge pursuant
to which Mr. Young will provide consulting services to East Ridge for a period
of five years and for which he will receive $75,000 annually  payable in equal
monthly installments.  Under the terms of the consulting agreement, Mr. Young
will be available to Cornerstone to consult with it on general banking matters,
marketing issues, customer contacts and personnel and other management issues.
Mr. Young is not required to provide any minimum amount of such services or
work any specific number of hours under such consulting agreement and is merely
to make himself available upon reasonable notice.
         
         Mr. Young also has the right to sell the shares of New Cornerstone
Common Stock he receives in the Merger back to New Cornerstone over a
three-year period at $12.55 (46,745 shares), $14.00 (28,356 shares) and $16.00
(21,756) per share in years 1998, 1999 and 2000, respectively.  New Cornerstone
has the option to redeem such shares during the same period at the same prices. 
No other East Ridge shareholders who receive shares of New Cornerstone Common
Stock will have the same opportunity to require New Cornerstone to redeem their
shares.  New Cornerstone will reimburse Mr. Young for any interest expense he
incurs in connection with the debt he incurred to purchase substantially all of
his shares of East Ridge Common Stock if the Merger does not close by August
12, 1997.  Cornerstone is a participant in a $3,750,000 commercial bank loan to
Mr. Young, the proceeds of which were used to purchase East Ridge Common Stock. 
Cornerstone's participation is $750,000.  New Cornerstone will also reimburse
Mr. Young for his attorneys fees incurred in connection with the Merger.  See
"The Merger -- Interests of Certain Persons in the Merger."

   
         Pursuant to the Change-in-Control Protective Agreements (the
"Protective Agreement"), Messrs. Renegar, James R. Young, Jr. and Crye are
entitled to receive an aggregate of up to $300,000 under certain circumstances. 
However, it is presently  anticipated that Messrs. Renegar, James R. Young, Jr.
and Crye will continue their employment with Cornerstone Community Bank after
the Merger and their current employment agreements will remain in effect. 
Nevertheless, each is entitled to severance benefits in the event he elects to
terminate his employment within 30 days after the consummation of the Merger or
within 90 days of the Merger if he terminates his employment for "Good Reason." 
"Good Reason" is defined in the Protective Agreement as (i) the requirement that
the employee move his personal residence, or perform his principal executive
functions, more than 30 miles from his primary office as of the date of the
Change in Control; (ii) a reduction of more than 10% in the employee's base
compensation as in effect on the date of the Change in Control; (iii) the
failure by the successor corporation to provide the employee with compensation
and benefits substantially similar to those provided to him by East Ridge; or
(iv) a failure to elect the employee to the board of directors of the successor
corporation if the employee is serving on such board at the time of the Change
in Control.  Additionally, the employee is entitled to the severance benefit in
the event his employment is terminated without "Just Cause" as defined in the
Protective Agreement during the period beginning six months before a Change in
Control and ending on the second anniversary of the Change in Control.  David E.
Young will receive $75,000 per year for 5 years under his consulting agreement
in lieu of severance benefits under the Continuation Agreement since his
employment will be terminated as a result of the Merger.  See "The Merger --
Interests of Certain Persons in the Merger."

        Additionally, Messrs. David E. Young, Renegar and James R. Young are
parties to Executive Salary Continuation Agreements (the "Continuation  
Agreement") and Mr. Crye is a party to a Survivor Income Agreement each of which
provide salary continuation benefits in the event the executive remains in the
employ of East Ridge during his lifetime or until retirement at the age of 70. 
In the event the employment of the executive is terminated prior to retirement,
the executive is entitled to a certain percentage of the benefits depending on
his length of employment.  See "The Merger -- Interests of Certain Persons in
the Merger." 
    

CERTAIN DIFFERENCES IN SHAREHOLDERS' RIGHTS

         Upon the effectiveness of the Merger, shareholders of Cornerstone,
a Tennessee banking corporation, will become shareholders of New Cornerstone
(formerly, East Ridge), a Tennessee corporation, and their rights as
shareholders of New Cornerstone will be determined by the Tennessee Business
Corporation Act ("TBCA") and by New Cornerstone's Charter and Bylaws, as
amended and restated pursuant to the Merger Agreement, rather than the
Tennessee Banking Act ("TBA") and the rules and regulations of the FDIC.  The
rights of shareholders of Cornerstone currently differ from rights of the
shareholders of East Ridge with respect to certain important matters, including
their rights to remove and elect directors, call annual meetings, inspect
corporate books and records, amend the charter and bylaws, dissolve the
corporation, take action without a meeting, receive dividends, require
appraisal or dissent with respect to their shares, and approve the
corporation's undertaking of conflict-of-interest transactions; the required
shareholder votes as to certain matters; indemnification provisions; and
statutory and other restrictions on certain business combinations and share
acquisitions.  For a summary of these differences, see "Effect of the Merger on
Rights of Shareholders."

         Upon the effectiveness of the Merger, shareholders of East Ridge who
elect to receive shares of New Cornerstone Common Stock will be governed by the
Amended and Restated Charter of New Cornerstone and Amended and Restated Bylaws
of New Cornerstone as provided in the Merger Agreement.  Their rights as
shareholders of East Ridge will continue to be determined by the TBCA.

DISSENTERS' RIGHTS

         Under the TBCA, holders of East Ridge Common Stock who vote against
the Merger and who deliver to East Ridge the required written demand and who
otherwise comply with the requirements of the TBCA will be entitled to receive
the value of their shares in cash as determined under the provisions of the
TBCA.  SUCH RIGHT WILL BE LOST, HOWEVER, IF THE PROCEDURAL REQUIREMENTS OF THE
TBCA ARE NOT FULLY AND PRECISELY SATISFIED.  See "The Merger -- Dissenters'
Rights" and Appendix C.

         Under the TBA, holders of Cornerstone Common Stock who vote against
the Merger and who deliver to Cornerstone the required written demand and who
otherwise comply with the requirements of the TBCA will be entitled to receive
the value of their shares in cash as determined under the provisions of the
TBCA. SUCH RIGHT WILL BE LOST, HOWEVER, IF THE PROCEDURAL REQUIREMENTS OF THE
TBCA ARE NOT FULLY AND PRECISELY SATISFIED.  See "The Merger -- Dissenters'
Rights" and Appendix C.

CERTAIN FEDERAL INCOME TAX CONSEQUENCES

        Cornerstone and East Ridge have received an opinion of counsel that for
federal income tax purposes the Merger will be treated as a reorganization
within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as
amended (the "Code"), and, accordingly, for federal income tax purposes,
neither shareholders of Cornerstone nor shareholders of East Ridge will
recognize gain or loss upon the receipt of New Cornerstone Common Stock, except
to the extent of any cash received in exchange for shares of East Ridge Common
Stock or cash received in lieu of fractional shares.  In addition, the exchange
of the Cornerstone warrants for New Cornerstone Warrants may not be considered
to be part of the reorganization under present federal income tax regulations,
and, therefore, gain or loss may be recognized on this exchange.  Consummation
of the Merger is dependent upon, among other conditions, receipt by East Ridge
and Bank of East Ridge of an opinion of counsel substantially to this effect. 
East Ridge shareholders who elect to receive cash in exchange for their shares
of East Ridge Common Stock may incur tax as a result of the exchange.  In
addition, the exchange of Cornerstone warrants for New Cornerstone Warrants is
not considered to be part of the reorganization under the present federal
income tax regulations, and, therefore, this exchange may not be tax-free.

         East Ridge and Cornerstone shareholders are urged to consult their own
tax advisers as to the specific tax consequences to them of the Merger,
including the applicability and effect of federal, state, local and other tax
laws.  See "The Merger -- Certain Federal Income Tax Consequences."

ACCOUNTING TREATMENT

         The Merger will be accounted for as a purchase and is a "reverse
acquisition" where the acquirer is deemed to be Cornerstone in view of the 79.4%
ownership interest of the Cornerstone shareholders in New Cornerstone after the
Merger.   See "The Merger -- Accounting Treatment."

MARKET PRICES OF COMMON STOCK

  Neither the East Ridge Common Stock nor the Cornerstone Common Stock is
listed, traded or quoted on any securities exchange or in the over-the-counter
market, and no dealer makes a market in either Common Stock, although isolated
transactions between individuals occur from time to time.  To East Ridge
management's knowledge, the most recent transaction with respect to East Ridge
Common Stock was at $56.17 per share; and to Cornerstone management's
knowledge, the most recent transaction with respect to Cornerstone Common Stock
was $13.50 per share.  The shares of New Cornerstone Common Stock and New
Cornerstone Warrants to be issued hereunder are registered under the Securities
Act of 1933, as amended (the "1933 Act"), but it is not anticipated that a
trading market for either will develop.

EQUIVALENT AND PRO FORMA SHARE DATA

  The following table presents selected comparative unaudited per share data
for East Ridge Common Stock and Cornerstone Common Stock on a historical basis,
and for New Cornerstone Common Stock on a pro forma combined basis giving
effect to the Merger [on a purchase accounting basis] as a "reverse
acquisition" where the acquirer is deemed to be Cornerstone in view of the
79.4% ownership interest of the Cornerstone shareholders in New Cornerstone
after the Merger.  The data are not necessarily indicative of the results of
the future operations of the combined entity or the actual results that would
have occurred had the Merger been consummated prior to the periods indicated.

</TABLE>

       At June 30, 1997, East Ridge's total assets decreased 2.66%.  This is due
to a decrease in deposits, which in turn decreased the flow of funds into cash
and cash equivalent balances.  The deposit decrease is due to the maturing of
certificates of deposit, which were generated during 1996 when Bank of East
Ridge offered competitive prices to customers.

       The six months of 1997 reflect net income of $229,000.  This is
consistent with the net income of $109,000 for the first three months of 1997. 
Noninterest income increased an additional $45,000 due to the sale of an SBA
loan during the second quarter of 1997.  Noninterest expense increased due
to additional professional fees generated during the second quarter of 1997. 
No other material changes occurred in the results of operations for the six 
months ended June 30, 1997.

</TABLE>

        At June 30, 1997, Cornerstone's total assets increased be approximately
$5.6 million from total assets at March 31, 1997.  The increase was primarily
attributable to an increase in loan demand.  Loans were approximately $27.5
million compared to approximately $22.1 million at March 31, 1997.
Cornerstone's net income for the six months ended June 30, 1997 increased to
$40,000 from net income of $11,000 at March 31, 1997.  This increase is
primarily attributable to an increase in interest-earning assets.

                                  RISK FACTORS

ABSENCE OF EXISTING PUBLIC MARKET; MARKET PRICES

  There is no existing market for the New Cornerstone Common Stock.
Application has not been made to list the New Cornerstone Common Stock on the
NASDAQ National Market or on any other stock exchange.  There can be no
assurance that an active and liquid trading market for the New Cornerstone
Common Stock will develop.  Further trading prices of the New Cornerstone
Common Stock will depend on many factors including, among other things, the
operating results and financial condition of New Cornerstone and the market for
similar securities.  There can be no assurance as to the market price for the
New Cornerstone Common Stock.

ABILITY OF NEW CORNERSTONE TO EXECUTE ITS BUSINESS STRATEGY

  The financial performance of New Cornerstone will depend in part on New
Cornerstone's ability to successfully integrate the operations and management
of Cornerstone Community Bank and Bank of East Ridge.  There can be no
assurance that New Cornerstone will be able to effectively and profitably
integrate the operations and management of Cornerstone Community Bank and Bank
of East Ridge.

INTEREST RATE RISK

  Banking companies' earnings depend largely on the relationship between the
cost of funds, primarily deposits, and the yield on earning assets.  This
relationship, known as the interest rate spread, is subject to fluctuation and
is affected by economic and competitive factors which influence interest rates,
the volume and mix of interest-earning assets and interest-bearing liabilities,
and the level of nonperforming assets.  Fluctuations in interest rates may
affect the demands customers have for banking companies' products and services.
East Ridge and Cornerstone are, and New Cornerstone will be, subject to
interest rate risks to the degree that interest-bearing liabilities reprice or
mature more slowly or more rapidly or on a different basis than its
interest-earning assets.  Given East Ridge's and Cornerstone's current volume
and mix of interest-bearing liabilities and interest-earning assets, interest
rate spread could be expected to increase during times of rising interest rates
and, conversely, to decline during times of falling interest rates.  Although
both East Ridge and Cornerstone believe their current levels of interest rates
sensitivity is reasonable, significant fluctuations in interest rates may have
an adverse effect on their respective results of operations.

ECONOMIC CONDITIONS AND GEOGRAPHIC CONCENTRATION

  East Ridge's operations are located and concentrated primarily in the
Chattanooga, Tennessee area, which include the counties of Hamilton in
Tennessee, and Catoosa and Walker in Georgia.  Cornerstone's operations are
located and concentrated primarily in Hamilton County, Tennessee.   As a result
of the geographic concentration, East Ridge's and Cornerstone's results depend
largely upon economic conditions in these areas.  A deterioration in economic
conditions in these market areas could have a materially adverse impact on the
quality of the loan portfolio and the demand for products and services, and,
accordingly, the results of operations.  See "Information Concerning East
Ridge" and "Information Concerning Cornerstone."

GOVERNMENT REGULATIONS AND MONETARY POLICY

  The banking industry is subject to extensive federal and state supervision
and regulation.  Such regulation limits the manner in which East Ridge, Bank of
East Ridge and Cornerstone conduct their respective businesses, undertake new
investments and activities, and obtain financing.  This regulation is intended
primarily for the protection of the deposit insurance fund and consumers, and
not to benefit the holders of East Ridge's and Cornerstone's securities.
Financial institution regulation has been the subject of significant
legislation in recent years, and may be the subject of further significant
legislation in the future, none of which is in the control of East Ridge or
Cornerstone.  Significant new laws or changes in, or repeals of, existing laws
may cause East Ridge's and Cornerstone's results to





                                     - 11 -
<PAGE>   25

differ materially.  Further, federal monetary policy, particularly as
implemented through the Federal Reserve System, significantly affects credit
conditions for East Ridge and Cornerstone, primarily through open market
operations in the United States government securities, the discount rates for
bank borrowings and bank reserve requirements, and a material change in these
conditions would be likely to have a material impact on East Ridge's and
Cornerstone's results of operations.  See "Information Concerning East Ridge -
Supervision and Regulation" and "Information Concerning Cornerstone -
Supervision and Regulation."

COMPETITION

  The banking and financial services business in the Chattanooga area
generally, and East Ridge's and Cornerstone's market areas specifically, is
highly competitive.  The increasingly competitive environment is a result
primarily of changes in regulation, changes in technology and product delivery
systems, and the accelerating pace of consolidation among financial services
providers.  East Ridge and Cornerstone compete for loans, deposits and
customers and delivery of financial services with other commercial banks,
savings and loan associations, securities and brokerage companies, mortgage
companies, insurance companies, finance companies, money market funds, credit
unions, and other non-bank financial service providers.  Many of these
competitors are much larger in total assets and capitalization, have greater
access to capital markets and offer a broader array of financial services than
either East Ridge or Cornerstone.  There can be no assurance that East Ridge,
Cornerstone or New Cornerstone, after the Merger, will be able to compete
effectively and the results of operations of each could be adversely affected
if circumstances affecting the nature or level of competition change.  See
"Information Concerning East Ridge - Competition" and "Information Concerning
Cornerstone - Competition."

DEPENDENCE ON KEY PERSONNEL

  After the Merger, New Cornerstone's success will depend substantially
on certain members of its senior management, in particular, Timothy L. Hobbs,
Earl A. Marler, Jr. and Carolyn C. Johnson.  New Cornerstone's business and
financial condition could be materially adversely affected by the loss of the
services of either of such individuals.  New Cornerstone does not anticipate
maintaining key person life insurance.  See "Management of Cornerstone."

CREDIT QUALITY

  A significant source of risk for East Ridge and Cornerstone arises from the
possibility that losses will be sustained because borrowers, guarantors and
related parties may fail to perform in accordance with the terms of their
loans.  Both East Ridge and Cornerstone have adopted underwriting and credit
monitoring procedures and credit policies, including the establishment and
review of the allowance for credit losses that management of each believes are
appropriate to minimize this risk by assessing the likelihood of
nonperformance, tracking loan performance and diversifying each company's
credit portfolio.  Such policies and procedures, however, may not prevent
unexpected losses that could materially adversely affect East Ridge's and
Cornerstone's results of operations and the results of operations of New
Cornerstone after the Merger.

ANTI-TAKEOVER PROVISIONS.

  The Amended and Restated Charter of New Cornerstone and the Amended and
Restated Bylaws of New Cornerstone will contain provisions which may make New
Cornerstone a less attractive target for acquisition by anyone who does not
have the support of New Cornerstone's Board of Directors, including a
requirement of the super majority vote of shareholders or directors for the
approval of certain acquisitions of shares of common stock. Additionally,
holders of New Cornerstone Common Stock who were formerly shareholders of
Cornerstone will become subject to several state statutes which provide
anti-takeover protection for Tennessee corporations.  See "Effect of the Merger
on the Rights of Shareholders."

   
FUTURE FINANCING NEEDS

  While there is no current plan to do so, New Cornerstone may, in the future,
incur indebtedness.  The degree to which New Cornerstone becomes leveraged
could have important consequences to holders of New Cornerstone Common Stock,
including: (i) New Cornerstone's ability to obtain financing to meet regulatory
capital requirements, for working capital, capital expenditures, acquisitions,
general corporate purposes or other purposes may be impaired in the future; (ii)
a substantial portion of New Cornerstone's cash flow from operations could be
dedicated to the payment of principal of and interest on any such future
borrowings, thereby reducing the funds available to New Cornerstone for its
operations and other purposes; and (iii) New Cornerstone could be unable to
adjust to rapidly changing market conditions and could be vulnerable in the
event of a downturn in general economic conditions or its business.

VOTING REQUIREMENTS AT MEETINGS

  At the East Ridge Meeting, approval and adoption of the Merger Agreement
requires the affirmative vote of a majority of the outstanding shares of East
Ridge and the election of each of the six nominees to serve on the East Ridge
Board requires the affirmative vote of the holders of a plurality of the votes
cast.  The presence at the East Ridge Meeting, in person or by proxy, of the
holders of a majority of the total number of shares of East Ridge Common Stock
outstanding on the East Ridge Record Date will constitute a quorum for the
transaction of business by such holders at the East Ridge Meeting.  On the East

his shares in favor of the Merger.  Accordingly, approval of the Merger
Agreement by the East Ridge shareholders is assured.

  At the Cornerstone Meeting, approval and adoption of the Merger Agreement and
approval of the amendment to the Cornerstone Charter to authorize the exercise
of trust powers require the affirmative vote of the holders of a majority of
the outstanding shares of Cornerstone Common Stock and the election of each of
the 16 nominees to serve on the Cornerstone Board requires the affirmative vote
of the holders of a plurality of the votes cast.  The ratification of the
appointment of auditors requires that votes cast in favor of the proposal
exceed votes cast against the proposal.  The presence at the Cornerstone
Meeting, in person or by proxy, of the holders of a majority of the total
number of shares of Cornerstone Common Stock outstanding on the Cornerstone
Record Date will constitute a quorum for the transaction of business by such
holders at the Cornerstone Meeting.  On the Cornerstone Record Date, there were
590,130 outstanding shares of Cornerstone Common Stock, each holder of which is
entitled to one vote per share with respect to each matter to be voted on at

  At the Meetings, abstentions will be counted as present for quorum purposes,
but will have the same effect as a vote "against" the proposal to approve the
Merger Agreement. Broker "non-votes" will not be considered present for quorum
purposes and will have the same effect as a vote "against" the proposal to
approve the Merger Agreement.  A "broker non- vote" refers to shares
represented at the Meetings in person or by proxy by a broker or nominee where
such broker or nominee (i) has not received voting instructions on a particular
matter from the beneficial owners or persons entitled to vote and (ii) the
broker or nominee does not have the discretionary voting power on such matter.

                            PROPOSAL 1. THE MERGER

  The following information concerning the Merger, insofar as it relates to
matters contained in the Merger Agreement, is qualified in its entirety by
reference to the Merger Agreement which is incorporated herein by reference and
attached hereto as Appendix A.  Cornerstone and East Ridge shareholders are
urged to read carefully the Merger Agreement.

BACKGROUND OF AND REASONS FOR THE MERGER

  Background.

  Historically, the ownership of East Ridge has been concentrated in the hands 
of four directors, holding approximately 70% of the outstanding shares. 
Management held less than 5% of such outstanding shares.  In late 1994, one of
the directors holding approximately 40% of the outstanding shares of East Ridge
was approached concerning the sale of his shares.  This director did not sell
his shares but the possibility of a sale of control of East Ridge began to
concern management with regard to the future direction of East Ridge.
Management began to explore the possibility of acquiring East Ridge and made
numerous inquiries as to the financing of such acquisition.  These efforts were
unsuccessful.  In September 1995, David E. Young, Chairman of Bank of East
Ridge and a director of East Ridge, in a further effort to maintain Bank of
East Ridge as a community bank, negotiated options to acquire 74,629 shares of
East Ridge Common Stock from the four major shareholders who were also members
of the East Ridge Board at an exercise price of $35 per share.  The options
were for an initial term of six months, with a six month extension.

  At this point, Mr. Young began an active search for potential acquirors of
East Ridge and contacted a total of six regional and community banks to solicit
proposals to acquire East Ridge.  During the period from September 1995 through
the summer of 1996, Mr. Young received acquisition proposals in the range of
$5.2 million to $6 million from three of the institutions.  None of these
proposals was accepted by the East Ridge Board.

  Cornerstone opened on February 20, 1996, with the purpose of becoming a
community bank for the entire Chattanooga area.  Organizers of Cornerstone
believed that early opportunities to expand Cornerstone in the greater
community should be explored to implement its growth plan.  The Cornerstone
Board was aware that the possibility existed to acquire Bank of East Ridge,
which had been formed to serve as a community bank, and believed that this
acquisition offered the distinct advantage of combining two local community
banks, consistent with the original intent of the Cornerstone organizers to
become a community bank.
 
  The Cornerstone Board appointed Directors Amin, Hobbs, Marler, Pollard and
Wiggins (the "Cornerstone Special Committee") to contact Mr. Young to explore
the feasibility of a business combination.  The Cornerstone Special Committee
first met with Mr. Young on February 29, 1996 to explore the possibility of a
transaction.  The Committee was informed that a group of directors of East
Ridge, holding the majority of the outstanding stock of East Ridge, was seeking
cash for its holdings.  The Cornerstone representatives determined that the best
approach would involve the offer of a combination of both cash and stock.    

   
  In April 1996, Mr. Young exercised his option with two of the optionors for a
total of 21,620 shares and tendered his promissory notes in the aggregate
principal amount of $756,700 in payment for such option shares.  These
promissory notes matured on January 31, 1997 and provided for interest at the
rate of 6.5% per annum.  The promissory notes were secured by a pledge of the
shares acquired under the options.  Also in April 1996, Mr. Young entered into
amendments to the options with the other two optionors pursuant to which (i)
the option term was extended until January 31, 1997 and (ii) the optionors were
granted the right to share in the proceeds of any subsequent resale of the
option stock in excess of $35.00 per share. Based upon the exchange ratio set
forth in the Merger Agreement, Mr. Young has paid or will pay an additional
$11.08 per share acquired under such option agreements as so amended.
    

  Subsequent meetings between the Cornerstone Special Committee and Mr. Young
were held on April 10 and 17, 1996, at which there were further discussions
concerning the consideration available for a proposed transaction and its
acceptability to both parties.

                                     - 15 -
<PAGE>   29

  At its regular meeting on April 22, 1996, the Special Committee recommended
that the Cornerstone Board make an offer to East Ridge of $6.1 million to be
paid 75% in stock and 25% in cash.  The Cornerstone Board believed that upon
completion of an arrangement combining the banks, it would advance its business
plan by approximately 36 months.  The Cornerstone Board also believed that the
two banks were similar in philosophies and cultures.  The combination would
result in additional operating facilities and branch locations for Cornerstone,
which currently has one 3,500 square foot branch location, and would provide
immediate and adequate space for support services thereby relieving Cornerstone
from having to develop these on its own.  

  On May 2, 1996, the Cornerstone Special Committee and Mr. Young met again to
explore the possibilities of a combination.  Subsequently the Cornerstone
Special Committee informed the Cornerstone Board on May 20, 1996 that its offer
had been rejected because the East Ridge Board had determined that the amount
of stock offered by Cornerstone did not provide the liquidity the East Ridge
shareholders desired.  However, the Cornerstone Board increased its offer to
$6.25 million, with the proposed transaction consideration in the form of 50%
cash and 50% stock.  East Ridge rejected the revised offer and discussions
between the parties terminated for the remainder of 1996.

   
  In September 1996, the East Ridge Board engaged Alex Sheshunoff & Company 
("Sheshunoff") of Austin, Texas as its financial adviser.  Sheshunoff
is a nationally recognized analyst of financial institutions furnishing
investment banking and other financial services to the banking industry. 
Neither East Ridge nor the Bank of East Ridge had a prior investment banking
relationship with Sheshunoff.  Sheshunoff prepared a confidential memorandum
relating to East Ridge and Bank of East Ridge in order to solicit offers to
purchase East Ridge.  Sheshunoff submitted its memorandum to approximately 12
potential acquirors.  As a result of this solicitation of interest, proposals
from four institutions were received valuing East Ridge in a range of $5
million to $6 million.  In a series of meetings during the fall of 1996, the
East Ridge Board determined to reject all of the submitted proposals in its
belief that none of them reflected the true value of East Ridge.  In rendering
services to East Ridge, Sheshunoff did not provide an appraisal of East Ridge
or Bank of East Ridge nor did it provide a fairness opinion with respect
to any acquisition proposals solicited by it.  Since no acquisition transaction
resulted from its efforts, under the terms of its engagement, Sheshunoff
received no compensation for its solicitations on behalf of East Ridge.
    

  At the end of 1996, management of East Ridge explored the possibility of
electing sub-chapter S tax status for East Ridge in order to reduce East
Ridge's tax burden, thereby facilitating management's attempt to finance the
acquisition of control of East Ridge.  In furtherance of this plan,
approximately 2,700 shares of East Ridge Common Stock were redeemed at $35 per
share in order to reduce the total number of shareholders to less than 75 as
required by relevant tax law.  However, because of uncertainties concerning
potential adverse tax consequences and continued inability to secure
satisfactory financing, this plan was abandoned.

  At the January 20, 1997 meeting, the Cornerstone Board determined to inquire
of East Ridge if discussions could be reopened.  Director Wiggins contacted
James Watkins, then the Chairman of East Ridge, who informed him that all
negotiations would be handled by Mr. Young.  Thereafter, on January 24, 1997,
Mr. Wiggins met with Mr. Young to discuss reopening the discussions between the
parties.  On January 30, 1997, Messrs. Wiggins, Hobbs and Marler from
Cornerstone met with Mr. Young from East Ridge. In conjunction with these
negotiations, Cornerstone agreed to finance Mr. Young's purchase of shares
under the remaining outstanding options and the payment of his notes to other
former optionors.  The amount of such financing totaled $3,750,000 with
Cornerstone's participation in the aggregate amount of $750,000.

  A subsequent meeting was held at the law offices of Miller & Martin in
Chattanooga on February 3, 1997.  Attending this meeting were Messrs. Young,
Wiggins, Hobbs, and Marler from Cornerstone and Ms. Kathryn Edge and W. Scott
McGinness, from Miller & Martin law firm who represented Mr. Young and East
Ridge. Also present was Mark McDowell, a consultant engaged by Cornerstone to
assist in the negotiating process.  Colman Hoffman from Baker, Donelson,
Bearman and Caldwell, the legal representative of Cornerstone, was connected by
telephone for the entire meeting.  During this meeting, the parties discussed
the transaction, including the structure and amount and form of consideration
which was stock and up to approximately 70% of the consideration in cash for an
aggregate consideration of approximately $6.125 million.

  The same group with the exception of Mr. McDowell, but with Mr. Hoffman
present in person, reconvened on February 6, 1997, at the Miller & Martin law
offices with the intent of finalizing the terms of a transaction.  An agreement
in principle was reached at this time subject to the approval of the two
Boards.

  A special Cornerstone Board meeting was called on February 10, 1997 and the
agreement in principle was approved with a unanimous vote with twelve of the
sixteen directors in attendance. The other four directors approved the
agreement within the next couple of days.

  On February 12, 1997, Mr. Young entered into a Stock Purchase Agreement with
Cornerstone relative to the purchase of his shares of East Ridge Common Stock on
terms identical to those set forth in the Merger Agreement.  Thereafter on
February 13, 1997, representatives of Cornerstone including Messrs. Marler,
Hobbs and Wiggins, and Colman Hoffman and Bill Carriger, attorneys for
Cornerstone, met with the East Ridge Board, at which meeting terms of the
proposed transaction were discussed in detail.  The East Ridge Board determined
that the Cornerstone proposal was superior to its prior proposals because the
proportion of cash to be received by the shareholders of East Ridge was
significantly higher than in the prior proposals.  The East Ridge Board
approved the proposal as described and recommended its acceptance by the East
Ridge shareholders.  The East Ridge Board further authorized the executive
officers, with the advice of counsel, to negotiate, execute and deliver for and
on behalf of East Ridge a definitive agreement with respect to the proposal.

   
  The East Ridge Board discussed the advisability of retaining a financial 
advisor to assist it with respect to the proposed transaction and to
render an opinion as to its fairness from a financial point of view to the
unaffiliated shareholders of East Ridge.  However, the East Ridge Board
determined that it was not necessary to engage a financial advisor for such
purpose since the East Ridge Board had previously retained Sheshunoff as its
financial advisor and Sheshunoff to its satisfactory had not been able to 
obtain any acquisition proposals superior to the Cornerstone proposal which is
valued at $6.125 million, exclusive of amounts paid to Mr. Young under his 
Consulting Agreement.  Additionally management of East Ridge conducted, or
caused to be conducted, a due diligence investigation of the Cornerstone loan
and securities portfolios to its satisfaction.                       
    

   
  The East Ridge Board determined that the Merger is fair to and in the best
interest of East Ridge and its unaffiliated shareholders despite the fact that
David E. Young, the principal shareholder of East Ridge, negotiated the
transaction and negotiated favorable terms for himself, including a consulting
arrangement and the right to require New Cornerstone to redeem shares of New
Cornerstone Common Stock which he receives in the Merger, that do not apply to
unaffiliated East Ridge shareholders. For information on the interests of
certain officers and directors of East Ridge, including Mr. Young, in the
Merger, see" - Interests of Certain Persons in the Merger."
    

  The transaction was publicly announced on Sunday, February 16, 1997, in the
Chattanooga Free Press and the Merger Agreement was formally approved and
adopted by the Cornerstone Board at its March meeting.

  The Cornerstone Board approved the Merger Agreement on March 18, 1997 and
recommended its approval by the Cornerstone shareholders.  On March 18, 1997,
East Ridge, Bank of East Ridge and Mr. Young entered into the Merger Agreement
with Cornerstone, subject to East Ridge Board approval, and terminated the
earlier Stock Purchase Agreement between Cornerstone and Mr. Young.  At a
meeting held on March 24, 1997, the East Ridge Board approved the Merger
Agreement, effective March 18, 1997 and recommended its approval by the East
Ridge shareholders.

  Reasons for the Merger -- Cornerstone.  In reaching its determination that
the Merger and Merger Agreement are fair to, and in the best interest of,
Cornerstone and its shareholders, the Cornerstone Board consulted with its
legal and financial advisers, as well as with Cornerstone management, and
considered a number of factors, including, without limitation, the following:

  A.  the Cornerstone Board's review, based in part on the presentation by
Cornerstone management regarding its due diligence of East Ridge, of the
business, operations, earnings and financial conditions of East Ridge on both a
historical and prospective basis, the enhanced opportunities for operating
efficiencies (particularly in terms of integration of operations, data
processing and support functions, although the Cornerstone Board did not
quantify such anticipated operating efficiencies) that could result from the
Merger, the enhanced opportunities for growth that the Merger would make
possible and the respective contributions the parties would bring to a combined
institution;

  B.  the Cornerstone Board's belief, based upon an analysis of the anticipated
financial effects of the Merger, that upon consummation of the Merger, New
Cornerstone and its banking subsidiary would be well capitalized institutions,
the financial positions of which would be in excess of all applicable
regulatory capital requirements;

  C.  the Cornerstone Board's belief that, in light of the reasons discussed
above, East Ridge was the most attractive choice as a long term affiliation
partner of Cornerstone;

  D.  the expectation that the Merger will generally be a tax-free transaction
of Cornerstone and its shareholders to the extent such shareholders receive
shares of New Cornerstone Common Stock.  (See "Certain Federal Income Tax
Consequences");

  E.  the current and prospective economic and regulatory environment and
competitive constraints facing the banking and financial institutions in
Cornerstone's market area; and

  F.  the recent business combinations involving financial institutions, either
announced or completed, during the past year in the United States, the State of
Tennessee and contiguous states and the effect of such combinations on
competitive conditions in Cornerstone's market area.


                                     - 17 -
<PAGE>   31


     The Cornerstone Board did not assign any specific or relative weight to
the foregoing factors in their considerations.

     Reasons for the Merger -- East Ridge.

   
        The East Ridge Board believes that the transaction contemplated in the
Merger Agreement is in the best interests of all the shareholders of East
Ridge, including the unaffiliated shareholders, and that it reflects a fair
price from a financial stand point for East Ridge as a whole, particularly when
compared to other proposals received in the past despite the fact that David E.
Young the principal shareholder of East Ridge, negotiated the transaction and
negotiated favorable terms for himself, including a consulting arrangement and
the right to require New Cornerstone Common Stock which he receives in the
Merger, that do not apply to unaffiliated East Ridge shareholders. For
information on the interests of certain officers and directors of East Ridge,
including Mr. Young, in the Merger, see" -- Interest of Certain Persons in the
Merger."
    

        The Merger enables East Ridge to remain a part of a community 
institution bank dedicated to the service of customers in the Hamilton 
County/North Georgia market. The East Ridge Board believes that the Merger
will also result in a more certain future for current employees of Bank of
East Ridge.

     Recommendation of the East Ridge Board and the Cornerstone Board.

     The Boards of Directors of both East Ridge and Cornerstone have approved
the Merger Agreement and both recommend that the respective shareholders of
East Ridge and Cornerstone vote FOR approval of the Merger Agreement.
David E. Young beneficially owns 76,139 shares of East Ridge Common Stock,
representing 69.8% of the outstanding shares and has agreed to vote all such
shares in favor of the Merger. Accordingly, approval of the Merger Agreement by
the shareholders of East Ridge is assumed.

OPINION OF CORNERSTONE FINANCIAL ADVISER

     Cornerstone retained Mercer to render its opinion as to the fairness, from
a financial point of view, to the holders of Cornerstone Common Stock of the
consideration to be paid in the Merger.  In connection with this engagement,
Mercer evaluated the financial terms of the Merger, but was not asked to, and
did not recommend the specific ratio of exchange between East Ridge and
Cornerstone common stocks and did not assist in the Merger negotiations.  The
ratio of exchange was determined by the East Ridge and Cornerstone Boards of
Directors after arm's length negotiations.  Cornerstone did not place any
limitations on the scope of Mercer's investigation or review.

     Mercer is a national valuation consulting and transaction advisory firm
which renders independent valuations and related financial advisory services,
including the issuance of fairness opinions for mergers and acquisitions, to
financial institutions and businesses throughout the United States.  Mercer was
formed in 1982 and was selected by the Cornerstone Board based upon Mercer's
extensive experience of preparing valuations, rendering fairness opinions, and
facilitating mergers by acting as transaction advisors to financial
institutions.

     Mercer has  provided the Cornerstone Board with a fairness opinion. THE
FULL TEXT OF THE OPINION LETTER OF MERCER, DATED APRIL 25, 1997, WHICH SETS
FORTH CERTAIN ASSUMPTIONS MADE, MATTERS CONSIDERED, AND LIMITATIONS ON THE
REVIEW PERFORMED, IS ATTACHED AS APPENDIX B.  THE SUMMARY OF THE OPINION OF
MERCER SET FORTH IN THIS JOINT PROXY STATEMENT/PROSPECTUS IS QUALIFIED IN ITS
ENTIRETY BY REFERENCE TO THE OPINION.

     Mercer did not compile nor audit Cornerstone's or East Ridge's financial
statements, nor independently verify the information reviewed.  Mercer relied
upon such information as being complete and accurate in all material respects.
Mercer did not make an independent evaluation of the loan portfolio or the
adequacy of the loan loss reserve, nor did it make specific evaluations of
other assets or liabilities of either company.  Mercer's opinion does not
constitute a recommendation to any shareholder as to how the shareholder should
vote on the Merger.  Mercer did not express an opinion as to the prices at
which any security of East Ridge, Cornerstone or New Cornerstone might trade in
the future.

     Mercer considered the following key issues in rendering the
fairness opinion: (i) terms of the Merger Agreement; (ii) an analysis of the
reasonableness of the proposed consideration which will be paid to East Ridge
shareholders; (iii) an analysis of the estimated pro forma changes in the
combined entities' balance sheet and income statement, book value per share,
earnings per share, and dividends per share from the perspective of the
Cornerstone shareholders based upon financial information as of March 31, 1997;
(iv) the tax-free nature of the transaction for Cornerstone shareholders with
respect to the New Cornerstone Common Stock; and (v) consideration of the
ability of the Merger to advance Cornerstone's business plan;

Transaction Overview

Among other things, the Merger Agreement provides for the following:

(i)  Cornerstone will merge into Bank of East Ridge with Bank of East Ridge as
the surviving corporation.  At closing, Bank of East Ridge will amend and
restate its charter and  change its name to "Cornerstone Community Bank."

(ii) East Ridge will amend its charter and adopt bylaws, both of which are
substantially similar to those currently in effect for Cornerstone, to increase
its authorized shares to 1,500,000, reduce the par value from $10.00 per share
to $1.00 per share, change the name of East Ridge to "Cornerstone Bancshares,
Inc." and





                                     - 18 -
<PAGE>   32

include other provisions satisfactory to Cornerstone.  The individuals serving
on the Cornerstone Board prior to the merger will comprise the board of
directors of New Cornerstone and Bank of East Ridge subsequent to the Merger.
      
(iii) Cornerstone shareholders will receive one share of New Cornerstone Common
Stock for each share of Cornerstone Common Stock.  In addition, Cornerstone
shareholders will receive a warrant to purchase additional New Cornerstone
Common Stock for $12 per share if exercised by February 8, 1998 and $15 per
share if exercised by February 8, 2001.  It is anticipated that New Cornerstone
shareholders will exercise approximately 180,000 of the outstanding New
Cornerstone Warrants at closing, the effect of which will be to increase
New Cornerstone's capital by $2.2 million.

(iv)  East Ridge shareholders will receive a total consideration of $6,125,000,
payable in cash of $56.1776 per existing share of East Ridge Common Stock, or
New Cornerstone Common Stock based upon the conversion ratio of $56.1776
divided by $12 per each share of existing East Ridge Common Stock.  A condition
of the Merger is that East Ridge shareholders owning at least 76,321 shares
(70%) elect the cash option.  If East Ridge shareholders elect to receive cash
greater than 70%, then the proceeds will be reduced on a pro rata basis with
the balance payable in the form of New Cornerstone Common Stock.  In the event
that East Ridge shareholders elect to receive less than 70% cash, then
Cornerstone may terminate the Merger Agreement.

(v)   David E. Young, Chairman of the Board of  Bank of East Ridge and a
director of East Ridge and East Ridge's largest shareholder with a 69.8%
interest, has agreed to exchange for cash at least 70% of the shares he owns.

(vi)  David E. Young has also agreed to be bound by a five year consulting
agreement for which he will receive consideration of $75,000 annually.  In
addition, change-of-control benefits totaling up to approximately $300,000 may
be paid to three Bank of East Ridge officers under certain conditions.

      The proposed purchase price for East Ridge is $6,125,000, or 12.6x East
Ridge's  reported 1996 net income and 200% of book value as of December 31,
1996.  As noted above, Mr. Young will receive $75,000 per year for five years
in connection with a consulting arrangement part of a non-compete agreement.
Based upon a discount rate of 7%, the present value of the after-tax payments
is about $191,000.  In addition, employment agreement payments may be incurred
for three officers, if they elect to terminate their relationship with Bank
of East Ridge within 30 days of the consummation of the merger.  The after-tax
liability of the payments approximates $189,000.

Valuation Analysis

      The valuation analysis of East Ridge is based upon an analysis of the
Comparable Transactions Method, involving the sale of banks and a Discounted
Cash Flow Method.  It should be emphasized that each analysis must be
considered in its entirety and that the overall fairness analysis is based upon
all factors considered, and not upon any particular valuation method.

      Comparable Transaction Analysis.  The comparable transaction method seeks
to develop an indication of value for a subject company by analyzing prices
paid for similar institutions which have been acquired.  With regard to the
banking industry, most transactions are measured in terms of price/book ratios
("P/B"),price/tangible book ratios ("P/TB") and price/earnings ratios ("P/E"). 
In addition, some analysts also consider pricing multiples for price/assets 
("P/A"), price/deposits ("P/D") and tangible book value premium/core deposits
("TBP/CD").

      Although the P/B ratio tends to be the more widely quoted pricing
multiple, the P/E ratio is generally more important, because acquirors are
most concerned with the target's earning capacity.  Also, the market's
relative pricing of the buyer (in relation to earnings) will dictate the size
of an offer before earnings dilution becomes an issue.

      With regard to banks, acquisition pricing in terms of P/E multiples
during the past ten years have been in the general vicinity of 14x to 16x
earnings, though there has been some upward pressure on multiples during 1996.





                                     - 19 -
<PAGE>   33
It should be noted that P/E ratios tend to vary outside this range when a 
seller's earnings are extremely high or low relative to the industry.  The
markets tend to maintain or lower P/E for high return on equity ("ROE") banks, 
keeping other relative measures of value in perspective.  Very high P/E ratios
are often seen when banks have temporarily depressed earnings and the market
expects future earnings to recover to more normal levels.

     In addition, P/B multiples will vary depending upon the amount of
equity employed by the seller.  P/B ratios tend to decline as equity rises (and
ROE declines) and increase when equity decreases (and ROE rises). In effect,
excess equity is often priced dollar-for-dollar by acquirors.

     With regard to East Ridge, Mercer reviewed prices paid for banks which
have been acquired as compiled by SNL Securities, LC, an analyst specializing
in securities of financial institutions.  The data was divided into six groups
with average and median P/E, P/B, P/TB, P/A, and TBP/CD ratios calculated for
calendar years 1992-1996: (i) all U.S. banks; (ii) Southeast based banks; (iii)
banks based in Alabama, Georgia and Tennessee; (iv) banks with $40 million to
$450 million of total assets and an equity/assets ratio of 9.0% to 13.0%; (v)
banks which were acquired for a combination of cash, common stock and other
securities; and, (vi) banks which were acquired for cash only.

     The table below presents a summary of the median P/E ratios and average
P/B, P/TB, P/A and TBP/CD ratios for the six acquisition groups as applied to
East Ridge's financial information for the fiscal year ended December 31, 1996.

</TABLE>

     The analysis indicates an overall range of estimated value of $5.2 
million to $9.2 million, with a range based upon averages only of $5.7 million
to $8.0 million.  The acquisition pricing for East Ridge falls within the
range.

     Discounted Cash Flow Analysis.  A discounted cash flow ("DCF") analysis was
also conducted to develop an estimate of value based upon the hypothetical cash
flow that East Ridge could produce for a controlling shareholder.  Value derived
using a DCF analysis is equal to the present value of any interim cash flows
(i.e., dividends) and the present value of a projected terminal value (i.e., the
estimated value of the subject at the end of the projection period). In
preparing its analysis, Mercer assumed that East Ridge operated "as is" without
considering any potential expense economies or revenue enhancements that an
acquiror might achieve.  Mercer assumed a deposit and asset growth rate of 5%
per year, less than that which has been recorded in recent years, and a slight
improvement in profitability from a return on assets ("ROA") of 1.15% in 1996 to
about 1.20% during the period.  Mercer does not represent or warrant that East
Ridge would achieve the results assumed in Mercer's analysis.


                                   - 20 -
<PAGE>   34

      Interim shareholder cash flows, consisting of dividends, are constructed 
so that East Ridge's consolidated equity/assets ratio of approximately 7.0% is
maintained. Accordingly, the projections assume that an acquiror could
distribute about two-thirds of earnings each year to maintain the targeted
capital ratio.

      The terminal value is derived by applying a P/E multiple to projected 2001
net income.  The cash flows were then discounted to their present values at a
risk adjusted rate (assumed to be in the vicinity of 14%-15% based upon current 
U.S. Treasury rates and an appropriate premium).  A summary of the results is 
presented in the table below.

      The center of the matrix reflects a reasonable range based upon a 
discount rate of 14% to 15% and a terminal value based upon a P/E multiple of 
14x to 15x. The indicated range is $6.0 million to $6.5 million.

Pro Forma Analysis

      Another important element of the overall fairness analysis is the expected
impact that the transaction will have on the combined banks' balance sheet,
earnings, and per share data.  Mercer does not represent or warrant that its
pro forma analysis would reflect that which is presented elsewhere in this
Joint Proxy Statement/Prospectus.  Mercer's analysis indicated the following:

(i)   The combined balance sheet will include approximately $82 million in
assets, which would be supported with approximately $9.4 million in equity
capital and $7.2 million in tangible equity capital.  The pro forma stated
equity-to-assets and tangible equity-to-tangible assets ratios would be,
respectively, 11.4% and 9.0%.

(ii)  Approximately $2.2 million of goodwill will be created, resulting in an
annual amortization expense of about $150,000 (assuming a 15 year straight line
amortization).

(iii) Cornerstone's pro forma earnings would increase from $44,000 as budgeted
for  1997 to over $340,000 after considering the impact of the foregone
interest income on cash paid to East Ridge shareholders, goodwill amortization,
and the increase in depreciation from the anticipated write-up of Bank of East
Ridge's main office.  Pro forma earnings will potentially be greater once
certain back office operations are combined.  Further, Cornerstone's business
plan projected $160,000 in expenses in 1997 and another $240,000 in expenses in
1998 for the opening of a second office in the Hamilton Mall/Gunbarrel Road
area.  Bank of East Ridge's supermarket branch in the area will allow
Cornerstone management to forego constructing a traditional branch in the area
for an undetermined period of time.






                                   - 21 -
<PAGE>   35


(iv)  Book value per share is projected to increase about a $1.00 per share;
however, tangible book value per share will decline by approximately $1.35 per
share.  As the goodwill is amortized, the difference between stated and
tangible book value per share will narrow.

(v)   Reported earnings per share and cash earnings per share (reported
earnings per share plus goodwill amortization) are projected to exceed what
they otherwise would have been.  The enhancement in earnings and per share
earnings is a key element in the fairness analysis because of the impact 
acceleration of the business plan (i.e., profitability) should have on the 
creation of shareholder value.

The Exchange Ratio

      Although the transaction essentially consists of a cash purchase, a
portion of the consideration paid will consist of New Cornerstone Common Stock
issued to East Ridge shareholders.  The exchange ratio is based upon a value of
$12.00 per share for Cornerstone (i.e., $56.1776 / $12.00).  Cornerstone
completed its initial stock offering in early 1996 when 590,130 shares were
sold for a price of $10.00 per share.  In addition, each share included a
non-detachable warrant, which can be exercised before February 1998 for an
additional share at $12.00 per share, or $15.00 per share for the following
three years before expiring.

      There has been limited trading in Cornerstone's shares since the original
share offering, with all transactions but one occurring at $12.00 per share.
The lone exception was one trade of 2,500 shares which occurred at $12.50 per
share.  If the exchange ratio were based upon $12.50 per share, then East Ridge
shareholders would receive approximately 147,000 shares versus 153,000 as
provided in the Merger Agreement.  Cornerstone shareholders would still receive
590,130 shares of New Cornerstone Common Stock, plus warrants for all
unexercised warrants.

      Mercer also analyzed the implied price multiples for Cornerstone Common
Stock.  At $12.00 per share, the shares are presently "priced" at 132% of book
value, 132% of tangible book value, 150x estimated 1997 earnings, and 20.3x
projected 1998 earnings.  Though the P/B multiple is below median P/B ratios
for publicly traded banks, the P/E ratios are well over the public multiples. 
Analysts and investors typically place the greatest emphasis on P/E ratios to
determine the relative attractiveness of a stock.

      Based upon the above, the exchange ratio appears to be reasonable from
the perspective of Cornerstone shareholders.

Statement of Disinterestedness

      For rendering its opinion, Cornerstone paid Mercer a professional fee of
$15,000 plus out-of-pocket expenses.  Neither Mercer nor its principals own an
interest in the securities of East Ridge or Cornerstone.

TERMS OF THE MERGER

   
      Merger Consideration Available to East Ridge Shareholders. At the 
Effective Time, each share of East Ridge Common Stock outstanding prior to the
Effective Time will be converted into a right to receive cash and/or New
Cornerstone Common Stock.  Shareholders of East Ridge who
    





                                     - 22-
<PAGE>   36

   
do not exercise dissenters' rights may elect to receive New Cornerstone Common
Stock and/or cash for their shares of East Ridge common stock.  The number of
shares of New Cornerstone Common Stock received in exchange for East Ridge
Common Stock will be based on an exchange ratio determined by multiplying the
number of shares of East Ridge Common Stock to be exchanged by $56.1772 and
then dividing by $12.00 (the "ERB Exchange Ratio").  The $12.00 per share price
for New Cornerstone Common Stock was based on the per share price of trades of
Cornerstone Common Stock which management of Cornerstone was aware of prior to
the execution of the Merger Agreement.  Shareholders of East Ridge who exchange
their shares for cash will receive $56.1772 per share.  Accordingly, each share
of East Ridge Common Stock will have converted into the right to receive 4.6814
shares of New Cornerstone Common Stock.  However, the aggregate amount of cash
to be delivered to the shareholders of East Ridge will not exceed $4,287,500. 
To the extent shareholders of East Ridge elect to receive in the aggregate more
than $4,287,500, cash will be paid on a pro-rata basis to those East Ridge
shareholders electing to receive cash.

      Although the Merger Agreement provides that in the event shareholders of
East Ridge elect less than $2,900,000 in cash, Cornerstone may terminate the
Merger Agreement, such eventuality is not likely to occur in that David E.
Young, who beneficially owns 76,139 shares of East Ridge Common Stock, or
approximately 69.8% of the outstanding shares of East Ridge has notified
Cornerstone that he intends to exchange at least 70% of the shares of East Ridge
Common Stock he owns for cash in the aggregate amount of $2,994,076.  However,
in the event the elections of the East Ridge shareholders, including Mr. Young,
for cash exceed $4,287,500, Mr. Young's election will be pro rated equally
with all other East Ridge shareholders who have elected cash.

      The Merger will result in a change in control of the ownership and
management of East Ridge.  Upon completion of the Merger, if all of the East
Ridge shareholders except Mr. Young who has agreed to exchange a certain
portion of his shares for cash, elect to receive all of the remaining 260,909
shares of New Cornerstone Common Stock issuable in the Merger, shareholders of
East Ridge will own a maximum of 20.6% of the outstanding shares of New
Cornerstone Common Stock and Cornerstone shareholders will own a 79.4% of the
outstanding shares of New Cornerstone Common Stock.  The officers and directors
of Cornerstone will continue as the officers and directors of New Cornerstone.

      Merger Consideration Available to Cornerstone Shareholders.  At the 
Effective Time, each share of Cornerstone Common Stock outstanding prior to the
Effective Time will be converted into a right to receive one share of New
Cornerstone Common Stock and one New Cornerstone Warrant exercisable for one
share of New Cornerstone Common Stock for $12 per share if exercised by
February 8, 1998 and for $15 per share if exercised by February 8, 2001.   New
Cornerstone Warrants exercisable for the purchase of up to 590,130 shares of
New Cornerstone Common Stock are issuable in the Merger.

      The Merger will result in a change in control of the ownership and
management of East Ridge.  Upon completion of the Merger, Cornerstone
shareholders will own a minimum of 79.4% of the outstanding shares of New
Cornerstone Common Stock and the officers and directors of Cornerstone will
continue as the officers and directors of New Cornerstone.      

      Fractional Shares.  No fractional shares of New Cornerstone Common Stock 
will be issued in connection with the Merger.  In lieu of fractional shares,
East Ridge will make a cash payment equal to the fractional interest which an
East Ridge shareholder would otherwise receive multiplied by $56.1772.  The
fractional interest will be determined after combining all shares owned by such
East Ridge shareholder.

ELECTION OF FORM OF MERGER CONSIDERATION

      As promptly as practicable after the Merger, New Cornerstone will provide
letters of transmittal to shareholders of East Ridge for the purpose of
exchanging their certificates of East Ridge Common Stock for New Cornerstone
Common Stock and/or cash as elected by the shareholder.  To the extent
shareholders of East Ridge elect to receive New Cornerstone Common Stock, such
election will be satisfied.  The amount of cash received by an East Ridge
shareholder is subject to the availability of cash to the extent shareholders
of East Ridge elect more than $4,287,500 in cash.  In such event, the amount of
cash up to the maximum amount of $4,287,500 will be pro-rated among all
shareholders of East Ridge, including Mr. Young, requesting cash.  In the event
all of the shareholders of East Ridge elect to receive cash for all of their
shares of East Ridge, each shareholder would receive 70% of his Merger
consideration in cash and 30% in New Cornerstone Common Stock.

      As promptly as practicable after the Merger, New Cornerstone will provide
letters of transmittal to shareholders of Cornerstone for the purpose of
exchanging their certificates of Cornerstone Common Stock and their warrants
for certificates representing New Cornerstone Common Stock and New Cornerstone
Warrants.  See "The Merger -- Surrender of Certificates."

ADVANTAGES AND DISADVANTAGES OF FORM OF MERGER CONSIDERATION

      To the extent shareholders of East Ridge elect New Cornerstone Common
Stock, they will not recognize gain or loss upon the receipt of New Cornerstone
Common Stock, except to the extent of any cash received in lieu of fractional
shares.  To the extent shareholders of East Ridge elect cash, they will
recognize gain or loss as a result of the Merger.  See "The Merger -- Certain
Federal Income Tax Consequences."

      Additionally, there is no market for the New Cornerstone Common Stock and
there is no assurance that an active and liquid market will develop. 
Therefore, East Ridge shareholders who elect to receive New Cornerstone Common
Stock and who desire to liquidate their investment may be unable to do so.  See
"Risk Factors."
    
                
EFFECTIVE TIME

      The Effective Time of the Merger will be 5:01 p.m., Eastern time, on the
later to occur of the acceptance for filing by the Secretary of State of the
State of Tennessee of articles of merger filed in accordance with the TBA, or
on such later date as the articles of merger may specify.  Unless otherwise
mutually agreed upon by East Ridge and Cornerstone, the Merger will occur on
the last business day of the month after all conditions contained in the Merger
Agreement have been satisfied or waived, including receipt of all regulatory
approvals and termination of all statutory waiting periods.

SURRENDER OF CERTIFICATES

      As promptly as practicable after the Merger, New Cornerstone,
acting in the capacity of exchange agent for both East Ridge and Cornerstone
(the "Exchange Agent"), will mail to each former holder of record of
Cornerstone Common Stock a form of letter of transmittal, together with
instructions for the exchange of such holder's certificates representing shares
of Cornerstone Common Stock for certificates representing shares of New
Cornerstone Common Stock and New Cornerstone Warrants.  The Exchange Agent will
also mail to each holder of record of East Ridge Common Stock a form of letter
of transmittal, together with instructions for the exchange of such holder's
certificates representing shares of East Ridge Common Stock for certificates
representing shares of New Cornerstone Common Stock and/or cash.

      HOLDERS OF CORNERSTONE COMMON STOCK AND EAST RIDGE COMMON STOCK SHOULD
HOLD THEIR CERTIFICATES UNTIL THEY RECEIVE THE LETTER OF TRANSMITTAL FORM AND
INSTRUCTIONS FROM THE EXCHANGE AGENT.

      Upon surrender to the Exchange Agent of one or more certificates for
Cornerstone Common Stock together with a properly completed letter of
transmittal, there will be issued and mailed to the holder of Cornerstone
Common Stock surrendering such items a certificate or certificates representing
the number of shares of New Cornerstone Common Stock and the number of New
Cornerstone Warrants to which such holder is entitled.

      Upon surrender to the Exchange Agent of one or more certificates for East
Ridge Common Stock together with a properly completed letter of transmittal,
there will be issued and mailed to the holder of East Ridge Common Stock
surrendering such items a certificate or certificates representing the number
of shares of New Cornerstone Common Stock to which such holder is entitled and,
where applicable, a check for the amount cash if the holder has elected to
receive cash.

      No dividend or other distribution payable after the Merger with
respect to either the Cornerstone Common Stock or the East Ridge Common Stock
will be paid to the holder of any unsurrendered certificate until the holder
surrenders such certificate(s), at which time the holder will be entitled to
receive all previously withheld dividends and distributions, without interest.

      After the Merger, there will be no transfers on either East Ridge's
or Cornerstone's stock transfer books of shares of either East Ridge Common
Stock or Cornerstone Common Stock issued and outstanding at the Merger.  If
certificates representing shares of either East Ridge Common Stock or
Cornerstone Common Stock are presented for transfer after the Merger, they will
be canceled and exchanged for the shares of New Cornerstone Common Stock or
cash deliverable in respect thereof as determined in accordance with the
provisions of the Merger Agreement.

      Neither East Ridge nor Cornerstone nor any other person will be liable to
any former holder of Cornerstone Common Stock or East Ridge Common Stock for
any amount properly delivered to a public official pursuant to applicable
abandoned property, escheat or similar laws.

      If a certificate for Cornerstone Common Stock or for East Ridge Common
Stock has been lost, stolen or destroyed, East Ridge will issue the
consideration properly payable in accordance with the Merger Agreement upon
receipt of appropriate evidence as to such loss, theft or destruction,
appropriate evidence as to the ownership of such certificate by the claimant,
and appropriate and customary indemnification.

may without the prior written consent of the other, among other things, (a)

with any persons; (d)  enter into or modify or permit any  subsidiary to enter
into or modify (except as may be required by applicable law and except for the
renewal of any existing plan or arrangement in the ordinary course of business
consistent with past practice) any pension, retirement, stock option, stock
purchase, savings, profit sharing, deferred compensation, consulting, bonus,
group insurance or other employee benefit, incentive or welfare contract, plan

      Immediately prior to the Effective Time and subject to the satisfaction
of the conditions precedent to closing, East Ridge shall cause Bank of East
Ridge to declare and pay a dividend to East Ridge at such time and in such
amount as may be requested by Cornerstone.  East Ridge shall take and shall
cause Bank of East Ridge to take all appropriate and necessary steps, including
without limitation, obtaining the requisite approval from the TDFI and the FDIC
for the declaration and payment of such dividend.

REGULATORY APPROVALS

      The Merger of Cornerstone and Bank of East Ridge is subject to prior
approval of the FDIC and TDFI.  Applications for such approval have been filed

      THERE CAN BE NO ASSURANCE THAT THE REGULATORY AUTHORITIES DESCRIBED ABOVE
WILL APPROVE THE MERGER, AND IF THE MERGER IS APPROVED, THERE CAN BE NO
ASSURANCE AS TO THE DATE OF SUCH APPROVAL.  THERE CAN ALSO BE NO ASSURANCE THAT
ANY SUCH APPROVALS WILL NOT CONTAIN A CONDITION OR REQUIREMENT WHICH CAUSES
SUCH APPROVALS TO FAIL TO SATISFY THE CONDITIONS TO CONSUMMATION OF THE MERGER
SET FORTH IN THE MERGER AGREEMENT.

NO SOLICITATION

      East Ridge is prohibited by the Merger Agreement from soliciting or

of a substantial equity interest in it or any business combination with it or
any of its subsidiaries other than as contemplated by the Merger Agreement.
East Ridge has agreed to notify Cornerstone immediately if any inquiries or
proposals as described above are received by, any such information is requested
from, or any such negotiations or discussions are sought to be initiated with,
East Ridge or Bank of East Ridge.

<PAGE>   40

WAIVER; AMENDMENT; TERMINATION

      Prior to the Merger, any provision of the Merger Agreement may be
(i) waived by the party benefitted by the provision or by both parties or (ii)
amended or modified at any time (including the structure of the transaction) by
an agreement in writing between the parties and approved by the Boards of
Directors (to the extent allowed by law), except that, after the vote by the
shareholders of East Ridge and Cornerstone, the Merger Agreement may not be
amended or revised to reduce the amount or change the form of the consideration
to be received by East Ridge's and Cornerstone's shareholders.

      The Merger Agreement may be terminated at any time prior to the Merger,
either before or after its approval by the holders of Cornerstone Common
Stock and East Ridge Common Stock, as follows: (a) by the mutual consent of
Cornerstone and East Ridge, if the Board of Directors of each so determines by
vote of a majority of the members of its entire Board; (b) in the event of the
failure of the shareholders of either Cornerstone or East Ridge to approve the
Merger Agreement by the requisite vote at their respective meetings called to
consider such approval, the Merger Agreement terminates automatically; or (c)
by Cornerstone or East Ridge, if its Board of Directors so determines by vote
of a majority of the members of its entire Board, in the event of a breach by
the other party hereto of any representation, warranty or agreement contained
herein which is not cured or not curable within sixty (60) days after written
notice of such breach is given to the party committing such breach by the other
party hereto which has or will have had a Material Adverse Effect on the
breaching party.

MANAGEMENT AFTER THE MERGER

      After the Merger, the directors and officers of Cornerstone will
become the directors and officers of New Cornerstone.

INTERESTS OF CERTAIN PERSONS IN THE MERGER

      Certain members of East Ridge's management and the East Ridge Board have
certain interests in the Merger that are in addition to their interests as
shareholders of East Ridge generally.  The East Ridge Board was aware of these
interests and considered them, among other matters, in approving the Merger
Agreement and the transactions contemplated thereby.

      Each of David E. Young, James D. Renegar, James R. Young, Jr. and Daniel
O. Crye is a party to a Change-in-Control Protective Agreement and an Executive
Salary Continuation Agreement which provides for certain payments in the event
their employment is terminated under certain circumstances after a change in
control of East Ridge.  Additionally, David E. Young will waive his right to
receive severance payments pursuant to the Change-in-Control Protective
Agreement and will enter into a consulting agreement with New Cornerstone
pursuant to which Mr. Young will provide consulting services to New Cornerstone
for a period of five years and for which he will receive $75,000 annually
payable in equal monthly  installments.  Under the terms of the consulting
agreement, Mr. Young will be available to Cornerstone to consult with it on
general banking matters, marketing issues, customer contacts and personnel and
other management issues.  Mr. Young is not required to provide any minimum
amount of such services or work any specific number of hours under such
consulting agreement and is merely to make himself available upon reasonable
notice.

      Additionally, Mr. Young is entitled to sell the shares of New Cornerstone
Common Stock he receives in the Merger back to New Cornerstone over a
three-year period at $12.55 (46,745 shares), $14.00 (28,356 shares) and $16.00
(21,756) per share in years 1998, 1999 and 2000, respectively.  New Cornerstone
has the option to redeem such shares during the same period at the same prices. 
No other East Ridge shareholders who receive shares of New Cornerstone Common
Stock will have the same opportunity to require New Cornerstone to redeem their
shares.  New Cornerstone will reimburse Mr. Young for any interest expense he
incurs in connection with the debt he incurred to purchase substantially all of
his shares of East Ridge Common Stock if the Merger does not close by August
12, 1997.  Cornerstone is a participant in a $3,750,000 commercial loan to Mr.
Young, the proceeds of which were used to purchase East Ridge Common Stock.
Cornerstone's participation is $750,000. New Cornerstone will also reimburse
Mr. Young for his attorneys fees incurred in connection with the Merger.

   
      Pursuant to the Change-in-Control Protective Agreements (the "Protective
Agreement"), Messrs.  Renegar, James R. Young, Jr. and Crye are entitled to
receive an aggregate of up to $300,000 under certain circumstances.  However,
it is anticipated that Messrs. Renegar, James R. Young, Jr. and Crye will
continue their employment with Conerstone Community Bank after the Merger and,
accordingly, their current employment agreements will remain in effect. 
Nevertheless, each is entitled to severance benefits in the event he elects to
terminate his employment within 30 days after the consummation of the Merger or
within 90 days of the Merger if he terminates his employment for "Good Reason." 
"Good Reason" is defined in the Protective Agreement as (i) the requirement
that the employee move his personal residence, or perform his principal
executive functions, more than 30 miles from his primary office as of the date
of the Change in Control; (ii) a reduction of more than 10% in the employee's
base compensation as in effect on the date of the Change in Control; (iii) the
failure by the successor corporation to provide the employee with compensation
and benefits substantially similar to those provided to him by East Ridge; or
(iv) a failure to elect the employee to the board of directors of the successor
corporation if the employee is serving on such board at the time of the Change
in Control.  Additionally, the employee is entitled to the severance benefit in
the event his employment is terminated without "Just Cause" as defined in the
Protective Agreement, during the period beginning six months before a Change in
Control and ending on the second anniversary of the Change in Control.  David
E. Young will receive $75,000 per year for 5 years under his consulting
agreement in lieu of severance benefits under the Continuation Agreement since
his employment will be terminated as a result of the Merger.See "The Merger --
Interests of Certain Persons in the Merger."

        Additionally, Messrs. David E. Young, Renegar and James R. Young are
parties to Executive Salary Continuation Agreements (the "Continuation  
Agreement") and Mr. Crye is party to a Survivor Income Agreement, each of which
provide salary continuation benefits in the event the executive remains in the
employ of East Ridge during his lifetime or until retirement at the age of 70. 
In the event the employment of the executive is terminated prior to retirement,
the executive is entitled to a certain percentage of the benefits depending on
his length of employment.  See "The Merger -- Interests of Certain Persons in
the Merger."

DISSENTERS' RIGHTS

      The following summary of applicable provisions of state law governing the
rights of shareholders is qualified in its entirety by reference to Appendix C.
Any shareholder of East Ridge entitled to vote on the Merger Agreement
has the right to receive payment of the fair value of his shares of East Ridge
Common Stock upon compliance with Sections 48-23-202 and 48-23-204 of the TBCA.
Additionally, Section 45-2-1309 of the TBA provides that shareholders of
Cornerstone have dissenters' rights as provided by the TBCA.  The following
discussion is applicable to shareholders of both East Ridge and Cornerstone.
For purposes of the discussion in this section only, East Ridge and Cornerstone
are referred to herein as "Corporation."  A shareholder may not dissent as to
less than all of the shares that he beneficially owns.  A nominee or fiduciary
may not dissent on behalf of any beneficial owner as to less than all of the
shares of such beneficial owner held of record by such nominee or fiduciary.  A
beneficial owner asserting dissenters' rights to shares held on his behalf must
submit to the Corporation the record shareholder's written consent to the
dissent not later than the time the beneficial shareholder asserts dissenters'
rights.  Any shareholder intending to enforce this right must not vote in favor
of the Merger Agreement and must file as written notice of his intent to demand
payment for his shares (the "Objection Notice") with the Corporate Secretary of
the Corporation either before the Annual Meeting or before the vote is taken at
the meeting.  The Objection Notice must state that the shareholder intends to
demand payment for his shares of common stock if the Merger is effected.  A
vote against approval of the Merger Agreement will not, in and of itself,
constitute an Objection Notice satisfying the requirements of Section 48-23-202
of the TBCA.  A failure to vote will not constitute a waiver of appraisal
rights as long as the requirements of Sections 48-23-101 through 48-23-302 of
the TBCA are complied with.  HOWEVER, ANY SHAREHOLDER WHO EXECUTES A PROXY CARD
AND WHO DESIRES TO EFFECT HIS APPRAISAL RIGHTS MUST MARK THE PROXY CARD
"AGAINST" THE PROPOSAL RELATING TO THE MERGER BECAUSE IF THE PROXY CARD IS LEFT
BLANK, IT WILL BE VOTED "FOR" THE PROPOSAL RELATING TO THE MERGER.

      If the Merger Agreement is approved, each shareholder who has filed an
Objection Notice will be notified by the Corporation of such approval within 10
days of the Annual Meeting (the "Dissenters' Notice").  The Dissenters' Notice
will (i) state where dissenting shareholders must (a) send the Payment Demand
(as defined below) and where and when they must (b) deposit their common stock
certificates (the "Certificates"), (ii) inform holders of uncertificated shares
of the extent of any restrictions on the transferability of such shares, (iii)
be accompanied by a form for demanding payment that includes the date of the
first announcement to the news media or to shareholders of the terms of the
proposed Merger, (iv) set a date by which the Corporation must receive the
Payment Demand, which may not be fewer than 1 or more than 2 months after the
date the Dissenters' Notice is delivered, and (v) be accompanied by a copy of
Sections 48-23-101 through 48-23-302 of the TBCA.  Within the time prescribed
in the Dissenters' Notice, a shareholder electing to dissent must make a demand
for payment (the "Payment Demand"), certify whether he acquired beneficial
ownership of the shares before February 16, 1997 (the date of the first public
announcement of the principal terms of the Merger Agreement), and deposit his
Certificates in accordance with the terms of the Dissenters' Notice.  Upon
filing the Payment Demand and depositing the Certificates, the shareholder will
retain all other rights of a shareholder until these rights are canceled or
modified by consummation of the Merger.  A Payment Demand may not be withdrawn
unless the Corporation consents.  FAILURE TO COMPLY WITH THESE PROCEDURES WILL
CAUSE THE SHAREHOLDER TO LOSE HIS DISSENTERS' RIGHTS TO PAYMENT FOR THE SHARES.
CONSEQUENTLY, ANY SHAREHOLDER WHO DESIRES TO EXERCISE HIS RIGHTS TO PAYMENT FOR
HIS SHARES IS URGED TO CONSULT HIS LEGAL ADVISER BEFORE ATTEMPTING TO EXERCISE
SUCH RIGHTS.

      As soon as the Merger is consummated, or upon receipt of a Payment
Demand, the Corporation shall, pursuant to Section 48-23-206, pay to each
dissenting shareholder who has complied with the requirements of Section
48-23-294 of the TBCA the amount that the Corporation estimates to be the fair
value of the shares of common stock, plus accrued interest.  Section 48-23-206
of the TBCA requires the payment to be accompanied by (i) certain of the
Corporation's financial statements, (ii) a statement of the Corporation's
estimate of fair value of the shares and explanation of how the interest was
calculated, (iii) notification of rights to demand payment, and (iv) a copy of
Sections 48-23-101 through 48-23-302 of the TBCA.  As authorized by Section
48-23-208, East Ridge and Cornerstone intend to delay any payments with respect
to any shares (the "after-acquired shares") held by a dissenting shareholder
which were not held by such shareholder on February 16, 1997, the date of the
first public announcement of the terms of the Merger Agreement.  When payments
are so withheld, Sections 48-23-208(b) and 48-23-209(a) will





                                     - 28 -
<PAGE>   42

require East Ridge and Cornerstone, as applicable,  after the Merger, to send
to the holder of the after-acquired shares an offer to pay the holder an amount
equal to East Ridge's or Cornerstone's estimate of their fair value plus
accrued interest, together with an explanation of the calculation of interest
and a statement of the holder's right to demand payment under Section
48-23-209.

      If the Merger is not consummated within two months after the date set for
demanding payment and depositing Certificates, the Corporation shall return the
deposited Certificates and release the transfer restrictions imposed on
uncertificated shares.  If, after returning deposited Certificates and
releasing transfer restrictions, the Merger is consummated, the Corporation
must send a new Dissenters' Notice and repeat the payment demand procedure.

      If the dissenting shareholder believes that the amount paid by the
Corporation pursuant to Section 48-23-206 or offered under Section 48-23-208 is
less than the fair value of his shares or that the interest due is calculated
incorrectly, or if the Corporation fails to make payment (or, if the Merger has
not consummated, the Corporation does not return the deposited Certificates or
release the transfer restrictions imposed on uncertificated shares) within two
months after the date set in the Dissenters' Notice, then the dissenting
shareholder may, within one month after (i) the Corporation made or offered
payment for the shares or failed to pay for the shares or (ii) the Corporation
failed to return deposited Certificates or release restrictions on
uncertificated shares timely, notify the Corporation in writing of his own
estimate of the fair value of such shares (including interest due) and demand
payment of such estimate (less any payment previously received).  FAILURE TO
NOTIFY THE CORPORATION IN WRITING OF A DEMAND FOR PAYMENT WITHIN ONE MONTH
AFTER THE CORPORATION MADE OR OFFERED PAYMENT FOR SUCH SHARES WILL CONSTITUTE A
WAIVER OF THE RIGHT TO DEMAND PAYMENT.

      If the Corporation and the dissenting shareholder cannot agree on a fair
price two months after the Corporation receives such a demand for payment, the
statute provides that the Corporation will institute judicial proceedings in a
court of record with equity jurisdiction in Hamilton County, Tennessee, (the
"Court") to fix (i) the fair value of the shares immediately before
consummation of the Merger, excluding any appreciation or depreciation in
anticipation of the Merger, and (ii) the accrued interest.  The "fair value" of
the common stock could be more than, the same as, or less than that produced by
the exchange ratios.  The Corporation must make all dissenters whose demands
remain unsettled parties to the proceeding and all such parties must be served
with a copy of the petition.  The Court may, in its discretion, appoint an
appraiser to receive evidence and recommend a decision on the question of fair
value.  The Court is required to issue a judgment for the amount, if any, by
which the fair value of the shares, as determined by the Court, plus interest,
exceeds the amount paid by the Corporation or for the fair value, plus accrued
interest, of his after-acquired shares for which the Corporation elected to
withhold payment.  If the Corporation does not institute such proceeding within
such two month period, the Corporation shall pay each dissenting shareholder
whose demand remains unsettled the respective amount demanded by each
shareholder.

      The Court will assess the costs and expenses of such proceeding
(including reasonable compensation for and the expenses of the appraiser by
excluding fees and expenses of counsel and experts) against the Corporation,
except that the Court may assess such costs and expenses as it deems
appropriate against any or all of the dissenting shareholders if it finds that
their demand for additional payment was arbitrary, vexatious or otherwise not
in good faith.  The Court may assess fees and expenses of counsel and experts
in amounts the Court finds equitable: (i) against the Corporation if the Court
finds that the Corporation did not substantially comply with the relevant
requirements of the TBCA or (ii) against either the Corporation or any
dissenting shareholder, if the Court finds that the part against whom the fees
and expenses are assessed acted arbitrarily, vexatiously or not in good faith.
If the Court finds that the services of counsel for any dissenter were of
substantial benefit to other dissenters and that the fees of such counsel
should be assessed against the Corporation, the Court may award reasonable fees
to such counsel to be paid out of amounts awarded to benefitted dissenters.

      THE FOREGOING SUMMARY OF THE APPLICABLE PROVISIONS OF THE TBCA IS NOT
INTENDED TO BE A COMPLETE STATEMENT OF SUCH PROVISIONS, AND IS QUALIFIED IN ITS
ENTIRETY BY REFERENCE TO SUCH SECTIONS, WHICH ARE INCLUDED AS APPENDIX C
HEREOF.

CERTAIN FEDERAL INCOME TAX CONSEQUENCES

        The federal income tax discussion set forth below represents a summary
of the opinion of Baker, Donelson, Bearman & Caldwell, a Professional
Corporation, counsel to Cornerstone.  It may not be applicable to a shareholder
who acquired his shares of East Ridge Common Stock or Cornerstone Common Stock
pursuant to the exercise of employee stock options or rights or otherwise as
compensation.  East Ridge and Cornerstone shareholders are urged to consult
their own tax advisers as to the specific tax consequences to them of the
Merger, including the applicability and effect of federal, state, local and
other tax laws.

        General.  It is the opinion of counsel that for federal income tax
purposes the Merger will be treated as a reorganization within the meaning of
Section 368(a) of the Code, and that, accordingly, (a) no gain or loss will be
recognized by those Cornerstone shareholders who receive New Cornerstone Common
Stock in exchange for Cornerstone Common Stock in connection with the Merger;
and (b) the tax basis of the New Cornerstone Common Stock to be received by
those Cornerstone shareholders who receive New Cornerstone Common Stock in
connection with the Merger will be the same as the basis in the Cornerstone
Common Stock surrendered in exchange therefor.  However, as more fully
discussed below in "Consequences of Warrant Exchange," the exchange of
Cornerstone warrants for New Cornerstone Warrants may not be tax free.  In
addition, it is the opinion of counsel that the exchange of East Ridge Common
Stock for New Cornerstone Common Stock pursuant to the Merger will be treated
as a recapitalization within the meaning of Section 368(a)(1)(E) of the Code
or as an exchange described in Section 1036(a) of the Code, and that,
accordingly, (a) no gain or loss will be recognized by those East Ridge
shareholders who receive only New Cornerstone Common Stock in exchange for East
Ridge Common Stock, and (b) the tax basis of the New Cornerstone Common Stock
to be received by those East Ridge shareholders who receive only New
Cornerstone Common Stock in connection with the Merger will be the same as the
basis in the East Ridge Common Stock surrendered in exchange therefor. 
Consequently, the holding period of any New Cornerstone Common Stock received
by the Cornerstone shareholders or the East Ridge shareholders in connection
with the Merger will include the holding period of the Cornerstone Common Stock
or East Ridge Common Stock, respectively, surrendered in exchange therefor,
provided that the Cornerstone Common Stock or East Ridge Common Stock is held
as a capital asset at the time of the Merger.  Consummation of the Merger is
dependent upon, among other conditions, receipt by East Ridge and the East
Ridge Board, for the benefit of the East Ridge shareholders, of an opinion of
counsel, substantially to this effect.

      Consequences of Receipt of Cash.

        Under the Merger Agreement, each East Ridge shareholder may elect to
take all or a portion of the amount payable to him or her in cash rather than
New Cornerstone Common Stock.  East Ridge shareholders electing to receive only
New Cornerstone Common Stock will receive only New Cornerstone Common Stock. 
East Ridge shareholders electing to receive only cash may, in certain
circumstances, receive both cash and New Cornerstone Common Stock.  The terms
and conditions of the cash election are more fully described in "The Merger --
Terms of the Merger."  If an East Ridge shareholder receives both cash and New
Cornerstone Common Stock in exchange for his East Ridge Common Stock, then gain
(but not loss) will be recognized by the shareholder, but not in an amount in
excess of the amount of cash received. The general rule is that any such gain
will be treated as capital gain, but if the exchange has the effect of the
distribution of a dividend, then the amount of gain recognized that is not in
excess of that shareholder's ratable share of the undistributed earnings and
profits of East Ridge will be treated as a dividend, taxable as ordinary
income, rather than capital gain.  The determination of whether the exchange
has the effect of the distribution of a dividend will be made on a
shareholder-by-shareholder basis in accordance with the principles enunciated
in Commissioner v. Clark, 109 S.Ct. 1455 (1989).  Any such gain will generally
be treated as a long-term capital gain provided that (i) the East Ridge Common
Stock was held by the shareholder as a capital asset on the date of the Merger,
(ii) the holding period for the shares of such East Ridge Common Stock was more
than one year, and (iii) if the shareholder had received New Cornerstone Common
Stock instead of cash and if the New Cornerstone Common Stock had been redeemed
immediately after the Merger, the redemption would have qualified as being
"substantially disproportionate" under Section 302(b)(2) of the Code.

        The substantially disproportionate test will be met by a shareholder
if, after the transaction, the shareholder will own less than fifty percent
(50%) of all New Cornerstone Common Stock and if his or her percentage
ownership of New Cornerstone Common Stock after the transaction will be less
than eighty percent (80%) of what his or her percentage ownership of East Ridge
Common Stock would have been if no East Ridge or Cornerstone shareholders
received cash and if no East Ridge or Cornerstone shareholders dissented.  In
applying the above test to determine whether a redemption is substantially
disproportionate, each shareholder will be considered to own not only the stock
which he or she actually owns, but





                                     - 30 -
<PAGE>   44

such shareholder also will be considered to constructively own stock from
certain related parties under Section 318 of the Code.  The related parties
whose stock ownership will be attributed to an individual shareholder include
the shareholder's spouse, children, grandchildren and parents and also include
partnerships, estates, trusts and corporations in which the shareholder has an
interest.  If the shareholder is an entity rather than a natural person, stock
owned by the persons holding an interest in the entity may be attributed to the
entity.  In either case, stock which is subject to an option may be attributed
to the option holder.  The constructive ownership rules may be applied more
than once so that stock which is attributed to one person or entity may, in
turn, be attributed to yet another person or entity.  Because both the
substantially disproportionate test and the constructive stock ownership rules
are very complex and the effect of these provisions will vary substantially     
based on each shareholder's individual circumstances, each East Ridge
shareholder electing to receive cash in whole or in part is urged to consult
his or her personal tax advisor as to whether or not any cash received may be
treated as a dividend.

      In the case of any East Ridge shareholder who receives both New 
Cornerstone Common Stock and cash, the shareholder's tax basis for the New
Cornerstone Common Stock received will be the same as the basis of all the
shares of East Ridge Common Stock owned by the shareholder, decreased by the
amount of cash received by the shareholder, increased by any amount that is
treated as a dividend and further increased by any amount of capital gain
which is recognized by the shareholder because of the Merger.

        If an East Ridge shareholder or a Cornerstone shareholder receives 
solely cash in exchange for his or her present Common Stock, either because of 
an election to receive all cash or because of the exercise of any right to 
dissent to the transaction, such cash will be treated as having been received 
as a distribution in redemption of New Cornerstone Common Stock, subject to the
provisions of Section 302 of the Code.  If, as a result of the distribution,
the shareholder owns no New Cornerstone Common Stock, either directly or by
reason of the constructive stock ownership rules under Section 318 of the Code,
the redemption will be a complete termination of interest within the meaning of
Section 302(b), and the cash will be treated as a distribution in full payment
in exchange for the shareholder's Common Stock.  Such shareholders will
recognize gain or loss measured by the difference between the amount of cash
received and the adjusted basis of the Common Stock surrendered.  As previously
discussed, the application of the constructive stock ownership rules are very
complex, and the effect of these rules will vary substantially based on each
shareholder's individual circumstances; therefore, each shareholder who will
receive solely cash in exchange for his or her shares of East Ridge Common
Stock or Cornerstone Common Stock is urged to consult his or her personal tax
advisor.

        Consequences of Receipt of Cash in Lieu of Fractional Shares.

        An East Ridge shareholder who is entitled to receive cash in lieu of a
fractional share interest of New Cornerstone Common Stock in connection with
the Merger will recognize, as of the date of the Merger, gain (or loss) equal to
the difference between such cash amount and the shareholder's basis in the
fractional share interest.  Any gain (or loss) recognized will be capital gain
(or loss) if the East Ridge Common Stock is held by such shareholder as a
capital asset at the date of the Merger.

        Consequences of Warrant Exchange

        Under Section 1.3541(e) of the Income Tax Regulations presently in
effect, stock warrants are not considered to be either stock or securities
which may be exchanged tax-free in a reorganization.  Accordingly, the Internal
Revenue Service has ruled in the past that an exchange of warrants of the
acquired corporation for warrants of the acquiring corporation should be
treated as a separable transaction from the reorganization and that gain or
loss on the exchange of warrants should be recognized.

        On December 23, 1996, the Internal Revenue Service proposed an
amendment to the Income Tax Regulations to treat warrants as securities which
could be exchanged tax-free in a reorganization.  However, there is no assurance
that these regulations will be adopted in their present proposed form.  In
addition, the proposed effective date for the regulations is 60 days after the
adoption of the final regulations.  There is no assurance that the regulations
will be adopted in time to apply to the exchange of Cornerstone warrants for
New Cornerstone Warrants.

        Accordingly, in view of the proposed but not yet effective amendments
to the Income Tax Regulations, counsel has expressed no opinion as to whether
any gain or loss will be recognized for federal income tax purposes on the
exchange of warrants for New Cornerstone Warrants.  In the event that the 
exchange of warrants is a taxable transaction, Cornerstone cannot make any
representation with respect to the value of the warrants or the gain or loss
realized on the exchange.  Each Cornerstone warrant holder is urged to consult
his or her personal tax advisor.

ACCOUNTING TREATMENT

      The transaction will be treated as a purchase for accounting purposes and
is a "reverse acquisition" where the acquirer is deemed to be Cornerstone in
view of the 79.4% ownership interest of the Cornerstone shareholders in New
Cornerstone after the Merger.

EXPENSES

      The Merger Agreement provides, in general, that East Ridge and
Cornerstone will each pay its own expenses in connection with the Merger
Agreement and the transactions contemplated thereby, except that East Ridge and
Cornerstone will divide equally the costs of printing this Joint Proxy
Statement/Prospectus and any other documents required in connection with the
Merger.

                      PROPOSAL 2. ELECTION OF DIRECTORS

EAST RIDGE

      A board of six directors will be elected at the East Ridge Meeting by the
holders of East Ridge Common Stock, to hold office until their successors have
been elected and qualified.  It is intended that, unless authorization to do so
is withheld, the proxies will be voted "FOR" the election of the director
nominees named below, each of whom is currently a director of East Ridge.  The
East Ridge Board believes that, if elected, each nominee will be willing to
serve.  The following persons have been nominated:

James L. Eidson, Sr.                         James D. Renegar
Jason D. Helton, Jr.                         Paul M. Starnes
William B. Luther                            David E. Young

CORNERSTONE

      A board of 15 directors will be elected at the Cornerstone Meeting by the
holders of Cornerstone Common Stock, to hold office until their successors have
been elected and qualified.  It is intended that, unless authorization to do so
is withheld, the proxies will be voted "FOR" the election of the director
nominees named below, each of whom is currently a director of Cornerstone.  The
Cornerstone Board believes that, if elected, each nominee will be willing to
serve.  The following persons have been nominated:

Ramesh V. Amin                               Russell W. Lloyd
Randy Brooks                                 Earl A. Marler, Jr.
B. Kenneth Driver                            Doyce G. Payne, M.D.
Karl Fillauer                                Bill Pollard
Timothy L. Hobbs                             Turner Smith
Carolyn C. Johnson                           Billy O. Wiggins
James H. Large                               Marsha Yessick
Lawrence D. Levine

             PROPOSAL 3. AMENDMENT OF THE CHARTER OF CORNERSTONE

      At the Cornerstone Meeting, shareholders will be asked to amend the
Charter of Cornerstone to authorize the exercise of trust powers.  While it is 
not anticipated that Cornerstone will immediately begin the operations of a
trust department, the Cornerstone Board believes that having the ability to
exercise trust powers is important for the implementation of Cornerstone's
focus on serving the banking needs of its customers.  The amendment to the
Charter is subject to the approval of the TDFI and the FDIC.  The Cornerstone
Board recommends a vote "FOR" the amendment to the Charter.

    PROPOSAL 4. RATIFICATION OF THE APPOINTMENT OF AUDITORS OF CORNERSTONE

      At the Cornerstone Meeting, shareholders will be asked to ratify the
appointment of Hazlett, Lewis & Bieter, PLLC, as Cornerstone's independent
certified public accountants.  Hazlett, Lewis & Bieter, PLLC, has served as the
independent accountants for Cornerstone since its inception on January 23,
1996.  The Cornerstone Board recommends a vote "FOR" the ratification of the
appointment of auditors as described herein.

   EAST RIDGE'S MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                           AND RESULTS OF OPERATIONS

GENERAL

         East Ridge's Management's Discussion and Analysis of Financial
Condition and Results of Operations should be read in conjunction with the
information and tables which follow.  For a discussion of liquidity and the
impact of inflation, see "Capital Resources/Liquidity" below.

SUMMARY

         Net income for 1996 was $486,000, a 42% increase from East Ridge's net
income of $343,000 in 1995.  Net income for 1995 was $124,000 or 57% higher
than the 1994 net income of $219,000.  Net income per common share for 1996 was
42% higher than in 1995 and in 1995 was 56% higher compared to 1994.  Pretax
income for 1996 increased $196,000 or 40% from 1995 and $141,000 or 40% from
1994 to 1995.  The larger increase in the 1995 net income over the 1995 pretax
income is attributable to a $67,000 increase in tax exempt interest income.

         The increase in net income from 1995 to 1996 is primarily due to an
increase in interest-earning assets of $4.215 million and only a 0.05% (tax
adjusted) decrease in the net interest margin.  The increase in net income from
1994 to 1995 was attributable to an increase in interest-earning assets of
$4.325 million offset somewhat by a decrease in the net interest margin by
0.29% (tax adjusted).  The 1995 increase was also due in part to a $26,000
decrease in the loan loss provision and decreases of $31,000 in the FDIC
assessment and $35,000 in computer rental expense offset by a decrease in
income from SBA loan sales of $59,000.

   
         The first three months of 1997 reflect net income of $111,000, 1.8%
more than the $109,000 earned for the first three months of 1996.  As of March
31, 1997, average federal funds sold increased by 289% as compared to March 31,
1996.  This led to the $38,000 increase in other interest income for 1997.  In
addition, noninterest income decreased by 29.4% as no SBA loans were sold during
the first three months of 1997, while income generated by SBA loan sales were
$45,000 during the first three months of 1996.  No other material changes
occurred in the results of operations or balance sheet during the first quarter
of 1997.
    
         For the remainder of the year in 1997, East Ridge will continue its
objectives of maintaining asset quality and providing superior customer service
to its markets.  New services have not been implemented during 1997 due to the
anticipated Merger.


FINANCIAL CONDITION

         Earning Assets.  Average earning assets in 1996 increased $4.2 million
or 12.5% over 1995 primarily due to an increase in average loans outstanding
and an increase in the average investment securities portfolio. The loan growth
was primarily funded by a significant increase in time deposits.  Average
earning assets in 1995 increased by $4.3 million or 14.7% over 1994 due
primarily to an increase in average investment securities.

         Loan Portfolio.  East Ridge's average loans for 1996 were $24.2
million, an increase of 10.4% over $21.9 million in average loans for 1995.
Loan growth for 1996 was primarily funded through increased deposit growth and
prepayments from mortgage-backed securities  and maturities in the investment
portfolio.  Real estate loans increased by $1.8 million or 12.3% over 1995.
Average loans for 1995 increased by $1.2 million over 1994, an increase of 
5.9%.  The increase in ending balance from 1995 to 1996 and 1994 to 1995 was 
consistent with the increase in average balances.

         Investment Portfolio.  East Ridge's investment securities portfolio
decreased by 17.9% or $2.3 million from 1995 to 1996.  The balance in the
securities portfolio decreased in order to fund loan growth.  The 1995
investment securities portfolio increased by $5.6 million over 1994, an
increase of 74.7%  The increase in deposits helped to fund the investment
securities portfolio growth.   East Ridge maintains an investment strategy of
seeking portfolio yields within acceptable risk levels, as well as providing
liquidity.  East Ridge maintains two classifications of investment securities:
"Held to Maturity" and "Available for Sale."  The "Available for Sale"
securities are carried at fair market value, whereas the "Held to Maturity"
securities are carried at book value. At year end 1996, unrealized gains in the
"Available for Sale" portfolio amounted to $15,000.  At the end of 1995 the
unrealized gains in the "Available for Sale" portfolio amounted to $47,000.

         Deposits.  East Ridge's average deposits increased $3.8 million or
10.9% from 1995 to 1996.  Average deposits increased $4.4 million or 14.7% from
1994 to 1995.  From year end 1995 to year end 1996, total deposits increased
$3.4 million or 9.3%.  The largest portion of growth during 1996 was in time
deposits that increased $2.6 million or 14.2%.  This is due to East Ridge's
strategy of increasing time deposits by offering competitive prices to



                                     - 33 -
<PAGE>   47

customers.  From 1995 to 1996 interest-bearing transaction deposits increased
$280,000 or 3.4%, savings deposits decreased $64,000 or 1.0% and other time
deposits of less than $100,000 increased $2.4 million or 16.9%.  From 1994 to
1995 interest-bearing transaction deposits increased $426,000 or 5.4%, savings
deposits decreased $1.329 million or 20.1%, other time deposits of less than
$100,000 increased $4.578 million or 47.1%, and time deposits of $100,000 or
more increased by $1.887 million or 109.1%.  The largest portion of deposit
growth was in time deposits.  This was also due to East Ridge's strategy of
offering better rates to increase time deposits.

         Capital Resources.  Stockholders' equity increased $397,000 or 15.0%
to $3.0 million as of December 31, 1996, compared with $2.6 million at the end
of 1995, and $2.2 million at year end 1994.  East Ridge purchased and retired
1,980 shares of common stock in 1996.  Retention of earnings accounted for all
the increase in stockholders' equity during 1996.

         A decrease in unrealized appreciation of "Available for Sale"
investment securities accounted for a decrease of $19,825 in stockholders'
equity as of December 31, 1996.  The changes in values in the unrealized
appreciation are not taken into account in determining regulatory capital
requirements.  Excluding the securities "Available for Sale" adjustment,
stockholders' equity was $3.0 million as of year end 1996, compared to $2.6
million for 1995, an increase of $417,000 or 15.9%.

         No new common stock was issued by East Ridge during 1996.

BALANCE SHEET MANAGEMENT

         Liquidity Management. Liquidity is the ability of a company to convert
assets into cash without significant loss and to raise funds by increasing
liabilities. Liquidity management involves having the ability to meet the
day-to- day cash flow requirements of its customers, whether they are
depositors wishing to withdraw funds or borrowers requiring funds to meet their
credit needs.

         The primary function of asset/liability management is not only to
assure adequate liquidity in order for East Ridge to meet the needs of its
customer base, but to maintain an appropriate balance between
interest-sensitive assets and interest-sensitive liabilities so that East Ridge
can profitably deploy its assets.  Both assets and liabilities are considered
sources of liquidity funding and both are, therefore, monitored on a daily
basis.

         The asset portion of the balance sheet provides liquidity primarily
through loan repayments and maturities of investment securities.  Additional
sources of liquidity are the investments in federal funds sold and prepayments
from the mortgage-backed securities from the investment portfolio.

         The liability portion of the balance sheet provides liquidity through
various interest bearing and noninterest bearing deposit accounts.  At year end
East Ridge had $1.0 million of federal funds available and a line of credit
from a commercial bank of which approximately $600,000 was available and
unused.

RESULTS OF OPERATIONS

         Net Interest Income.  Net interest income is the principal component
of a financial institution's income stream and represents the spread between
interest and fee income generated from earning assets and the interest expense
paid on deposits.  The following discussion is on a fully taxable equivalent
basis.

         Net interest income for 1996 increased $192,000 or 11.5% over 1995,
$129,000 or 8.3% in 1995 over 1994 and $235,000 or 17.9% in 1994 over 1993.
The increase in the net interest income from 1995 to 1996 is primarily due to
the increase in the interest-earning assets with a slight decrease in the net
interest margin.  The increase in the net interest income from 1994 to 1995 was
attributable to an increase in interest-earning assets offset by a 0.29%
decrease in the net interest margin.  See "Net Interest Income" for the detail 
of changes in interest income, interest expense





                                     - 34 -
<PAGE>   48

and net interest margin due to changes in volumes and rates, in addition to the
changes in interest-earning assets and interest-bearing liabilities.

   
         Interest  income increased $331,000 or 10.8% in 1996 from 1995, and
increased $595,000 or 24.0% in 1995 from 1994.  Interest income produced by the
loan portfolio increased $168,000 or 7.1% in 1996 from 1995, and increased
$328,000 or 16.1% in 1995 from 1994.  Interest income on investment securities
increased $201,000 or 32.9% from 1995 to 1996, and increased $192,000 or 45.8%
from 1994 to 1995.  The increase in investment income from 1994 to 1996 is due
to the increase in the average investment securities portfolio during the two
years.  Interest income-other increased by $38,000 for the three months ended
March 31, 1997 over March 31, 1996.  This was due to the average federal funds
sold increase of 289% as of March 31, 1997 as compared to March 31, 1996.  
Income from federal funds sold decreased $38,000 or 36.2% from 1995 to
1996 and increased $75,000 or 250% from 1994 to 1995.  The average federal
funds sold decreased from 1995 to 1996 which generated less in interest income.
For 1994 to 1995 average federal funds increased; therefore, the interest
income increased over the previous year.
    
         Total interest expense increased by $139,000 or 9.9% in 1996 from
1995, and increased $466,000 or 49.8% in 1995 from 1994.  The interest expense
increase from 1994 to 1996 is primarily due to the increase in average time
deposits.

         The trend in net interest income is commonly evaluated in terms of
average rates using the net interest margin and the interest rate spread.  The
net interest margin, or the net yield on earning assets is computed by dividing
fully taxable equivalent net interest income by average earning assets.  This
ratio represents the difference between the average yield on average earning
assets and the average rate paid for all funds used to support those earning
assets.  The net interest margin decreased 5 basis points in 1996 to 4.92%.
The net cost of funds, defined as interest expense divided by average-earning
assets,  decreased 1 basis point from 4.50% in 1995 to 4.49% in 1996.  The
yield on earning assets decreased 14 basis points to 8.99% in 1996 from 9.13%
in 1995.

         The interest rate spread measures the difference between the average
yield on earning assets and the average rate paid on interest bearing sources
of funds.  The interest rate spread eliminates the impact of noninterest
bearing funds and gives a direct perspective on the effect of market interest
rate movements.  During recent years, the net interest margins and interests
rate spreads have been under intense pressure to maintain historical levels,
due in part to tax laws that discouraged investment in tax-exempt securities
and intense competition for funds with non-bank institutions.  As a result of
changes in the asset and liability mix during 1996, the interest rate spread
decreased 13 basis points from 1995 to 1996.  The change in the asset and
liability mix during 1995 resulted in an interest rate spread decrease of 37
basis points.

         Allowance for Loan Losses.  Lending officers are responsible for the
ongoing review and administration of each loan.  They make the initial
identification of loans which present some difficulty in collection or where
there is an indication that the probability of loss exists.  Lending officers
are responsible for the collection effort on a delinquent loan.  Senior
management is informed of the status of delinquent and problem loans on a
monthly basis.

         Senior management makes recommendations monthly to the board of
directors as to charge-offs.  Senior management reviews the allowance for
possible loan losses on a quarterly basis.  East Ridge's policy is to
discontinue interest accrual when payment of principal and interest is 90 days
or more in arrears.

         The allowance for possible loan losses represents management's
assessment of the risks associated with extending credit and its evaluation of
the quality of the loan portfolio.  Management analyzes the loan portfolio to
determine the adequacy of the allowance for possible loan losses and the
appropriate provisions required to maintain a level considered adequate to
absorb anticipated loan losses.  In assessing the adequacy of the allowance,
management reviews the size, quality and risk of loans in the portfolio.
Management also considers such factors as loan loss experience, the amount of
past due and nonperforming loans, specific known risk, the status and amount of
nonperforming assets, underlying collateral values securing loans, current and
anticipated economic conditions and other factors which affect the allowance
for potential credit losses.





                                     - 35 -
<PAGE>   49


         While it is East Ridge's policy to charge off in the current period
the loans in which a loss is considered probable, there are additional risks of
future losses which cannot be quantified precisely or attributed to particular
loans or classes of loans.  Because these risks include the state of the
economy, management's judgment as to the adequacy of the allowance is
necessarily approximate and imprecise.

   
         Management believes that the $311,000 for March 31, 1997 and $296,000
for December 31, 1996 in the allowance for loan losses was adequate to absorb 
known risks in the portfolio.  No assurance can be given, however, that 
adverse economic circumstances will not result in increased losses in the loan
portfolio, and require greater provisions for possible loan losses in the 
future.

    
         Nonperforming Assets.  Nonperforming assets include nonperforming
loans and foreclosed real estate held for sale.  Nonperforming loans include
loans classified as nonaccrual or renegotiated.  East Ridge's policy is to
place a loan on nonaccrual status when it is contractually past due 90 days or
more as to payment of principal or interest.  At the time a loan is placed on
nonaccrual status, interest previously accrued but not collected is reversed
and charged against current earnings.  Recognition of any interest after a loan
has been placed on nonaccrual is accounted for on a cash basis.

   
         East Ridge had nonperforming assets at March 31, 1997 of $6,000 and
none as of December 31, 1996.
    

   
         Noninterest Income.  Noninterest income consists of revenues generated
from a broad range of financial services and activities including fee-based
services and profits and commissions earned through credit life insurance sales
and other activities.  In addition, gains or losses realized from the sale of
investment portfolio securities are included in noninterest income.  Total
noninterest income decreased by $42,000 or 29.4% for the three months ended
March 31, 1997 as compared to 1996, since no SBA loans were sold during the 
first three months of 1997 while income generated by SBA loan sales was $45,000
during the first three months of 1996.  Total noninterest income increased 
$16,000 or 3.6% in 1996 compared to 1995.  Noninterest income for 1995 showed 
decrease of $57,000 or 11.4% from 1994.
    
         Fee income from service charges on deposit accounts decreased $17,000
or 4.9% in 1996 following a $4,000 or 1.1% decrease in 1995.  Due to increased
competition, East Ridge lowered its service charge on small business accounts
in 1995 resulting in decreased service charge income in 1995 and  1996.
Nonrecurring items of noninterest income include sales of investment portfolio
securities; however, East Ridge did not realize any gains or losses from the
sales of securities in 1995 or 1996.  Included in other noninterest income are
gains on sales of the guaranteed portions of SBA loans.  In 1996 East Ridge
realized $45,000 from the sale of SBA loans.  There were no gains in 1995.

         Noninterest Expenses.  Noninterest expense for 1996 decreased $20,000
or 1.2% from 1995, decreased $76,000 or 4.7% in 1995 from 1994 and increased
$66,000 or 4.3% in 1994 from 1993.  Salaries and employee benefits in 1996
increased $30,000 or 3.3% from 1995 to a total of $931,000 at year-end 1996.
Salaries and employee benefits in 1995 decreased $14,000 or 1.5% from 1994.
The increase in 1996 was the result of normal pay increases.  The decrease in
1995 was due to a reduction in staff.

         Occupancy expense decreased by $18,000 or 18.5% in 1996 following an
increase of $2,000 or 2.3% in 1995.  Occupancy expense was lower in 1996 due to
a decrease in building repairs and maintenance.

         All other noninterest expenses decreased by $31,000 or 5.7% in 1996,
following a $65,000 or 10.7% decrease in 1995.  Included in all other
noninterest expense is FDIC insurance that in 1996 decreased $34,000 or 94.2%
from 1995.  The other expenses include supplies and printing, telephone,
postage and legal and audit fees.  The decrease in other noninterest expenses
was due to a concerted effort by senior management and staff to reduce
overhead.

EFFECTS OF INFLATION AND CHANGING PRICES

         Inflation generally increases the cost of funds and operating
overhead, and to the extent loans and other assets bear variable rates, the
yields on such assets.  Unlike most industrial companies, virtually all of the
assets and





                                     - 36 -
<PAGE>   50

liabilities of a financial institution are monetary in nature.  As a result,
interest rates generally have a more significant impact on the performance of a
financial institution than the effects of general levels of inflation.
Although interest rates do not necessarily move in the same direction or to the
same extent as the prices of goods and services, increases in inflation
generally have resulted in increased interest rates. At the beginning of 1996,
the Federal Reserve Board decreased interest rates 75 basis points in an effort
to enhance growth in the economy through monetary policy.  The prime rate
remained unchanged through 1996 and increased 25 basis points in the first
quarter of 1997.  In addition, inflation affects financial institutions' cost
of goods and services purchased, the cost of salaries and benefits, occupancy
expense and similar items.  Inflation and related increases in interest rates
generally decrease the market value of investments and loans held and may
adversely affect liquidity, earnings and stockholders' equity.  Mortgage
originations and refinancings tend to slow as interest rates increase and can
reduce East Ridge's earnings from such activities and the income from the sale
of residential mortgage loans in the secondary market.

LIABILITY AND ASSET MANAGEMENT

   The matching of assets and liabilities may be analyzed by examining the
extent to which such assets and liabilities are "interest rate sensitive" and
by monitoring an institution's interest rate sensitivity "gap."  An asset or
liability is said to be interest rate sensitive within a specific time period
if it will mature or reprice within that time period.  The interest rate
sensitivity gap is defined as the difference between the amount of
interest-earning assets maturing or repricing within a specific time period and
the amount of interest-bearing liabilities maturing or repricing within that
time period.  A gap is considered positive when the amount of interest rate
sensitive assets exceeds the amount of interest rate sensitive liabilities.  A
gap is considered negative when the amount of interest rate sensitive
liabilities exceeds the amount of interest rate sensitive assets.  During a
period of rising interest rates, a negative gap would tend to adversely affect
net interest income while a positive gap would tend to result in an increase in
net interest income.  During a period of falling interest rates, a negative gap
would tend to result in an increase in net interest income while a positive gap
would tend to adversely affect net interest income.

   The asset/liability committee, which consists of the president and one other
director and certain other officers is charged with monitoring the liquidity
and funds position of Bank of East Ridge.  The Committee regularly reviews (a)
the rate sensitivity position on a three-month, six-month, and one-year time
horizon; (b) loans to deposit ratios; and (c) average maturity for certain
categories of liabilities.

   The following table represents an interest sensitivity profile for East
Ridge as of December 31, 1996.  The table represents a static point in time and
does not consider other variables, such as changing spread relationships or
interest rate levels.  "Net repricing gap" is the difference between total
earning assets and total interest bearing liabilities repricing in any given
period and "cumulative gap" is the sum of the net repricing gap from period to
period.

Since interest-bearing demand deposits and savings accounts do not reprice on a
regular basis, these balances have been included in the "After 5 years and
non-rate sensitive" category.

INVESTMENT POLICY

         The objective of East Ridge's investment policy is to invest funds not
otherwise needed to meet the loan demand of Bank of East Ridge's market area to
earn the maximum return for Bank of East Ridge, yet still maintain sufficient
liquidity to meet fluctuations in Bank of East Ridge's loan demand and deposit
structure. In doing so, East Ridge balances the market and credit risk against
the potential investment return, makes investments compatible with the pledge
requirements of Bank of East Ridge's deposits of public funds, maintains
compliance with regulatory investment requirements, and assists the various
public entities with their financing needs. The Investment Committee is
comprised of the president and three other directors. The president is
authorized to execute security transactions for the investment portfolio and to
make decisions on purchases and sales of securities. All the investment
transactions occurring since the previous board of directors' meeting are
reviewed by the board at its next monthly meeting. Limitations on the
Committee's investment authority include: (a) investment in any one municipal
security may not exceed 20% of equity capital; (b) the entire investment
portfolio may not increase or decrease by more than 10% in



                                     - 43 -

any one month; (c) investments in obligations of the State of Tennessee may not
exceed 30% of equity capital; and (d) investment in mortgage-backed securities
may not exceed more than 40% of equity capital. The investment policy allows
portfolio holdings to include short-term securities purchased to provide Bank
of East Ridge's needed liquidity and longer term securities purchased to
generate stable income for Bank of East Ridge during periods of interest rate
fluctuations.

LOAN POLICY

         All lending activities of Bank of East Ridge are under the direct
supervision and control of the East Ridge Board with secondary authority vested
in the Executive Committee. The Senior Loan Committee, which consists of the
president, one other director and two senior lending officers, enforces loan
authorizations for each officer, decides on loans exceeding such limits,
services all requests for officer credits to the extent allowable under current
laws and regulations, administers all problem credits, and determines the
allocation of funds for each lending division. The loan portfolio consists
primarily of real estate, commercial, small business, residential construction
and consumer installment loans. Maturity of term loans is normally limited to
15 years. Conventional real estate loans may be made up to 80% of the appraised
value or purchase cost of the real estate for no more than a 30-year term.
Installment loans are based on the earning capacity and vocational stability of
the borrower.

         The Bank of East Ridge board at its regularly scheduled meetings
reviews all new loans made the preceding month. Loans which are 30 days or more
past due are reviewed monthly.

         The Loan Committee of Bank of East Ridge periodically reviews the loan
portfolio, particularly nonaccrual and renegotiated loans. Each loan officer is
responsible for monitoring and collecting his or her own loan portfolio. Loan
Committee review may result in a determination that a loan should be placed on
a nonaccrual status for income recognition, subject to East Ridge Board appeal. 
In addition, to the extent that management identifies potential losses in the
loan portfolio and reduces the book value of such loans through charge-offs, to
their estimated collectible value, East Ridge's policy is to classify as
nonaccrual any loan on which payment of principal or interest is 90 days or
more past due, where there is adequate collateral to cover principal and
accrued interest and the loan is in the process of collection. No concessions
are granted and late fees are collected. In addition, a loan will be classified
as nonaccrual if, in the opinion of the Loan Committee, based upon a review of
the borrower's or guarantor's financial condition, collateral value or other
factors, payment is questionable, even though payments are not 90 days or more
past due.

         When a loan is classified as nonaccrual, any unpaid interest is
reversed against current income. Interest is included in income thereafter only
to the extent received in cash. The loan remains in a nonaccrual classification
until such time as the loan is brought current, when it may be returned to
accrual classification. When principal or interest on a nonaccrual loan is
brought current, if in management's opinion future payments are questionable,
the loan would remain classified as nonaccrual. After a nonaccrual or
renegotiated loan is charged off, any subsequent payments of either interest or
principal are applied first to any remaining balance outstanding, then to
recoveries and lastly to income.

         The large number of consumer installment loans and the relatively
small dollar amount of each makes an individual review impracticable. It is
East Ridge's policy to charge off any consumer installment loan which is past
due 90 days or more.

         In addition, mortgage loans secured by real estate are placed on
nonaccrual status when the mortgagor is in bankruptcy, or foreclosure
proceedings are instituted. Any accrued interest receivable remains in interest
income as an obligation of the borrower.

CREDIT RISK MANAGEMENT AND RESERVE FOR LOAN LOSSES

         Credit risk and exposure to loss are inherent parts of the banking
business. Management seeks to manage and minimize these risks through its loan
and investment policies and loan review procedures. Management establishes and
continually reviews lending and investment criteria and approval procedures
that it believes reflect the risk sensitive nature of East Ridge. The loan
review procedures are set to monitor adherence to the established criteria and
to ensure that on a continuing basis such standards are enforced and
maintained.

         Management's objective in establishing lending and investment
standards is to manage the risk of loss and to provide for income generation
through pricing policies. To effectuate this policy, East Ridge makes
commercial real estate loans with a three-year or less fixed maturity which may
be amortized over a maximum of 15 years.

         The loan portfolio is regularly reviewed and management determines the
amount of loans to be charged-off. In addition, such factors as East Ridge's
previous loan loss experience, prevailing and anticipated economic conditions,
industry concentrations and the overall quality of the loan portfolio are
considered. While management uses available information to recognize losses on
loans and real estate owned, future additions to the allowance may be necessary
based on changes in economic conditions. In addition, various regulatory
agencies, as an integral part of their examination process, periodically review
the allowances for losses on loans and real estate owned. Such agencies may
require East Ridge to recognize additions to the allowances based on their
judgments about information available at the time of their examinations. In
addition, any loan or portion thereof which is classified as a "loss" by
regulatory examiners is charged-off.

   
         The reserve for loan losses is increased by provisions charged to
operating expense. The reserve is reduced by charging off loans or portions of
loans at the time they are deemed by management to be uncollectible and
increased when loans previously charged off are recovered. The resulting
reserve for loan losses is viewed by management as a single, unallocated
reserve available for all loans and, in management's opinion, is adequate to
provide for reasonably foreseeable potential loan losses.  The risk associated
with loans varies with the creditworthiness of the borrower, the type of loan
(consumer, commercial or real estate) and its maturity.  Cash flows adequate to
support a repayment schedule is an element considered for all types of loans. 
Real estate loans are impacted by market conditions regarding the value of the
underlying property used as collateral.  Commercial loans are also impacted by
the management of the business as well as economic conditions.  The approximate
anticipated amount of loan charge-offs by category during 1997 is as follows:

         Real Estate Loans                   $10,000
         Commercial and industrial loans           -
         All other loans                      48,000
                                             -------
           Total                             $56,000
                                             =======

         Management's estimate of charge-offs for 1997 is based upon historical
data as well as the composition of the loan portfolio at December 31, 1996. 
Management believes the allowance for loan lossess is adequate to absorb
such anticipated charge-offs.  
 
         Rules and formulas relative to the adequacy of  the reserve, although
useful as guidelines to management, are not rigidly  applied. The reserve for
loan losses was $311,000 as of march 31, 1997, or 1.24% of loans outstanding. 
The reserve for loan losses was $296,000 at year end 1996, or 1.17% of loans
outstanding compared to $307,000, or 1.35%, and $285,000, or 1.31%, at year
ends 1995 and 1994, respectively. The following table presents data related to
East Ridge's reserve for loan losses for the periods indicated.

</TABLE>

         The following table sets forth information with respect to
nonperforming loans of East Ridge on the dates indicated. Accrual of interest
is discontinued when there is reasonable doubt as to the full, timely
collections of interest or principal. When a loan becomes contractually past
due ninety (90) days with respect to interest or principal, it is reviewed and
a determination is made as to whether it should be placed on nonaccrual status.
When a loan is placed on nonaccrual status, all interest previously accrued but
not collected is reversed against current period interest income. Income on
such loans is then recognized only to the extent that cash is received and
where the future collection of principal is probable. Interest accruals are
resumed on such loans only when they are brought fully current with respect to
principal and interest and when, in the judgment of management, the loans are
estimated to be fully collectible as to principal and interest. Restructured
loans are those loans on which concessions in terms have been granted because
of a borrower's financial difficulty. Interest is generally accrued on such
loans in accordance with the new terms. The information provided below is as of
December 31 for the years indicated (dollars in thousands).

CAPITAL RESOURCES/LIQUIDITY

         Liquidity. Of primary importance to depositors, creditors and
regulators is the ability to have readily available funds sufficient to repay
fully maturing liabilities. East Ridge's liquidity, represented by cash and
cash due from banks,

is a result of its operating, investing and financing activities. In order to
insure funds are available at all times, East Ridge devotes resources to
projecting on a monthly basis the amount of funds which will be required and
maintains relationships with a diversified customer base so funds are
accessible. Liquidity requirements can also be met through short-term
borrowings or the disposition of short-term assets which are generally matched
to correspond to the maturity of liabilities.

         East Ridge has a formal liquidity policy, and in the opinion of
management, its liquidity levels are considered adequate. Neither East Ridge
nor Bank of East Ridge is subject to any specific regulation liquidity
requirements imposed by regulatory authorities. Bank of East Ridge is subject
to general FDIC guidelines which do not require a minimum level of liquidity.
Management believes its liquidity ratios meet or exceed these guidelines.
Management does not know of any trends or demands which are reasonably likely
to result in liquidity increasing or decreasing in any material manner.

         The following table sets forth liquidity ratios for the periods
indicated:

CAPITAL ADEQUACY

         Capital adequacy refers to the level of capital required to sustain
asset growth over time and to absorb losses. The objective of East Ridge's
management is to maintain a level of capitalization that is sufficient to take
advantage of profitable growth opportunities while meeting regulatory
requirements. This is achieved by improving profitability through effectively
allocating resources to more profitable businesses, improving asset quality,
strengthening service quality, and streamlining costs. The primary measures
used by management to monitor the results of these efforts are the ratios of
average equity to average assets, average tangible equity to average tangible
assets, and average equity to net loans.

         The Federal Reserve Board has adopted capital guidelines governing the
activities of bank holding companies. These guidelines require the maintenance
of an amount of capital based on risk-adjusted assets so that categories of
assets with potentially higher credit risk will require more capital backing
than assets with lower risk. In addition, banks and bank holding companies are
required to maintain capital to support, on a risk-adjusted basis, certain
off-balance sheet activities such as loan commitments.

         The capital guidelines classify capital into two tiers, referred to as
Tier I and Tier II. Under risk-based capital requirements, total capital
consists of Tier I capital which is generally common shareholders' equity less
goodwill and Tier II capital which is primarily a portion of the allowance for
loan losses and certain qualifying debt instruments. In determining risk-based
capital requirements, assets are assigned risk-weights of 0% to 100%, depending
primarily on the regulatory assigned levels of credit risk associated with such
assets. Off-balance sheet items are considered in the calculation of
risk-adjusted assets through conversion factors established by the regulators.
The framework for calculating risk-based capital requires banks and bank
holding companies to meet the regulatory minimums of 4% Tier I and 8% total
risk-based capital.

         In 1990 regulators added a leverage computation to the capital
requirements, comparing Tier I capital to total average assets less goodwill.

         The Federal Deposit Insurance Corporation Improvement Act of 1991
("FDICIA") established five capital categories for banks and bank holding
companies. The bank regulators adopted regulations defining these five capital
categories in September 1992. Under these new regulations each bank is
classified into one of the five categories based on its level of risk-based
capital as measured by Tier I capital, total risk-based capital, and Tier I
leverage ratios and its supervisory ratings.

employees. The employees are not represented by a collective bargaining unit.

operates two branches in Foodmax Supermarkets. These branches each are
comprised of approximately 450 square feet in each supermarket and are leased
pursuant to lease agreements entered into in August and November 1992 for
initial five year terms. Each lease provides two five year extensions. Bank of
East Ridge has renewed each such lease for the first renewal period.

LEGAL PROCEEDINGS

         The nature of its business generates a certain amount of litigation
against East Ridge and Bank of East Ridge involving matters arising in the
ordinary course of business. None of the legal proceedings currently pending or
threatened to which East Ridge or Bank of East Ridge is a party or to which any
of their properties are subject will have, in the opinion of management of East
Ridge, a material effect on the business or financial condition of East Ridge
or Bank of East Ridge.

special emphasis in retail banking, including the acceptance of checking and
savings deposits, and the making of commercial, real estate, personal, home
improvement, automobile and other installment and term loans. It also offers
collections, notary public services, and other customary bank services to its

<PAGE>   64



companies, credit unions and other financial institutions located in its
service area, which includes Hamilton County in Tennessee and Catoosa and
Walker Counties in Georgia.

SUPERVISION AND REGULATION

         East Ridge is a bank holding company within the meaning of the federal
Bank Holding Company Act of 1956, as amended (the "Act"), and is registered
with the Board of Governors of the Federal Reserve System (the "Board"). East
Ridge is required to file with the Board annual reports and such additional
information as the Board may require pursuant to the Act. The Board may also
make examinations of East Ridge and its subsidiaries. The following summary of
the Act and of the other acts described herein is qualified in its entirety by
express reference to each of the particular acts.

         The Act requires every bank holding company to obtain the prior
approval of the Board before acquiring direct or indirect ownership or control
of more than 5% of the voting shares of any bank which is not majority owned by
East Ridge. The Act prohibits a bank holding company, with certain exceptions,
from acquiring direct or indirect ownership or control of more than 5% of the
outstanding voting shares of any company which is not a bank and from engaging
in any business other than banking or furnishing services to or performing
services for its subsidiaries. The 5% limitation is not applicable to ownership
of shares in any company the activities of which the Board has determined to be
so closely related to banking or managing or controlling banks as to be a
proper incident thereto.

         Subject to limited exceptions, the Act prohibits the direct or
indirect acquisition by a bank holding company or any of its subsidiaries of
more than five percent of the voting shares or substantially all of the assets
of a bank located outside the state in which the operations of its banking
subsidiaries are principally conducted, unless the acquisition is specifically
authorized by a statute of the state in which the bank to be acquired is
located. The Tennessee Reciprocal Banking Act was amended, effective January 1,
1991, generally to permit nationwide reciprocal interstate banking.

         Bank of East Ridge is an "affiliate" of East Ridge within the meaning
of the Federal Reserve Act. This act places restrictions on a bank's loans or
extensions of credit to, purchases of or investments in the securities of, and
purchases of assets from an affiliate, a bank's loans or extensions of credit
to third parties collateralized by the securities or obligations of an
affiliate, the issuance of guarantees, acceptances, and letters of credit on
behalf of an affiliate, and certain bank transactions with an affiliate, or
with respect to which an affiliate acts as agent, participates, or has a
financial interest. Furthermore, a bank holding company and its subsidiaries
are prohibited from engaging in certain tie-in arrangements in connection with
any extension of credit, lease or sale of property or furnishing of services.

         Under Federal Reserve Board policy, East Ridge is expected to act as a
source of financial strength to its subsidiary bank and to commit resources to
support its subsidiary. This support may be required at times when, absent such
Federal Reserve Board policy, East Ridge may not be inclined to provide it.
Under the Financial Institutions Reform, Recovery, and Enforcement Act of 1989
("FIRREA"), a depository institution insured by the FDIC can be held liable for
any loss incurred by, or reasonably expected to be incurred by, the FDIC after
August 9, 1989 in connection with (a) the default of a commonly controlled
FDIC-insured depository institution or (b) any assistance provided by the FDIC
to any commonly controlled FDIC-insured depository institution "in danger of
default." "Default" is defined generally as the appointment of a conservator or
receiver and "in danger of default" is defined generally as the existence of
certain conditions indicating that a default is likely to occur in the absence
of regulatory assistance. Under FDICIA (see discussion below) a bank holding
company may be required to guarantee the capital plan of an undercapitalized
depository institution. Any capital loans by a bank holding company to any of
its subsidiary banks are subordinate in right of payment to deposits and to
certain other indebtedness of such subsidiary bank. In the event of a bank
holding company's bankruptcy, any commitment by the bank holding company to a
federal bank regulatory agency to maintain the capital of a subsidiary bank
will be assumed by the bankruptcy trustee and entitled to a priority of
payment.

<PAGE>   65



         Bank of East Ridge is a member of the FDIC and is subject to
examination and regulation by that authority. Bank of East Ridge is chartered
under the banking laws of the State of Tennessee and is subject to the
supervision of, and regular examination by, the TDFI.

         The Tennessee Reciprocal Banking Act requires the filing of an
application with and the approval of the Tennessee Commissioner of Financial
Institutions to acquire a Tennessee bank or bank holding company.

         Tennessee law was amended in 1990 to permit branch banking in any
county in the state. Prior to the amendment, statewide branching was possible
pursuant to a May 1988 federal court decision.

         In December 1991, a major banking bill entitled the Federal Deposit
Insurance Corporation Improvement Act of 1991 ("FDICIA") was enacted, which
substantially revises the bank regulatory and funding provisions of the Federal
Deposit Insurance Act and makes revisions to several other federal banking
statutes. Among other things, FDICIA requires the federal banking regulators to
take "prompt corrective action" in respect of depository institutions that do
not meet minimum capital requirements. The Bank of East Ridge has capital
levels well above the minimum requirements. In addition, an institution that is
not well capitalized is generally prohibited from accepting brokered deposits
and offering interest rates on deposits higher than the prevailing rate in its
market and also may not be able to "pass through" insurance coverage for
certain employee benefit accounts. FDICIA also requires the holding company of
any undercapitalized depository institution to guarantee, in part, certain
aspects of such depository institution's capital plan for such plan to be
acceptable. FDICIA contains numerous other provisions, including new
accounting, audit and reporting requirements, termination of the "too big to
fail" doctrine except in special cases, limitations on the FDIC's payment of
deposits at foreign branches, new regulatory standards in such areas as asset
quality, earnings and compensation and revised regulatory standards for, among
other things, powers of state banks, real estate lending and capital adequacy.
FDICIA also requires that a depository institution provide 90 days prior notice
of the closing of any branches.

EFFECT OF GOVERNMENTAL POLICIES

         East Ridge and Bank of East Ridge are affected by the policies of
regulatory authorities, including the Federal Reserve System. An important
function of the Federal Reserve System is to regulate the national money
supply. Among the instruments of monetary policy used by the Federal Reserve
are: purchases and sales of U.S. Government securities in the marketplace;
changes in the discount rate, which is the rate any depository institution must
pay to borrow from the Federal Reserve; and changes in the reserve requirements
of depository institutions. These instruments are effective in influencing
economic and monetary growth, interest rate levels and inflation.

         The monetary policies of the Federal Reserve System and other
governmental policies have had a significant effect on the operating results of
commercial banks in the past and are expected to continue to do so in the
future. Because of changing conditions in the national economy and in the money
market, as well as the result of actions by monetary and fiscal authorities, it
is not possible to predict with certainty future changes in interest rates,
deposit levels, loan demand or the business and earnings of East Ridge or
whether the changing economic conditions will have a positive or negative
effect on operations and earnings.

         Bills are pending before the United States Congress and the Tennessee
General Assembly which could affect the business of East Ridge and Bank of East
Ridge, and there are indications that other similar bills may be introduced in
the future. It cannot be predicted whether or in what form any of these
proposals will be adopted or the extent to which the business of East Ridge and
Bank of East Ridge may be affected thereby.

         No director of East Ridge is related to any other director.  David E.
Young is not related to James R. Young, Jr., identified below as Senior Vice
President of Bank of East Ridge.  No director of East Ridge is a director or
executive officer of another bank holding company, bank, savings and loan
association, or credit union. The following is a brief description of the
business experience of certain executive officers of East Ridge.

         DAVID E. YOUNG (62), is the Chairman of the Board of Bank of East
Ridge and a director of East Ridge. Mr. Young was Chairman of the Board of Bank
of East Ridge during its organization in 1984 and 1985 and was employed by Bank
of East Ridge in 1990 as its Chief Executive Officer.

         JAMES D. RENEGAR (59), is the Chairman of East Ridge and President of
Bank of East Ridge. Mr. Renegar was an organizer of Bank of East Ridge and has
been its President since the bank opened in 1985. He received a B.S. degree from

TRANSACTIONS WITH MANAGEMENT

         East Ridge has and expects to have in the future banking and other
business transactions in the ordinary course of its banking business with
directors, officers, and 10% beneficial owners of East Ridge and their
affiliates, including members of their families or corporations, partnerships,
or other organizations in which such officers or directors have a controlling
interest, on substantially the same terms (including price, or interest rates
and collateral) as those prevailing at the time for comparable transactions
with unrelated parties. Any such banking transactions will not involve more
than the normal risk of collectibility nor present other unfavorable features
to East Ridge.

LIABILITY AND ASSET MANAGEMENT

         The matching of assets and liabilities may be analyzed by examining
the extent to which such assets and liabilities are "interest rate sensitive"
and by monitoring an institution's interest rate sensitivity "gap." An asset or
liability is said to be interest rate sensitive within a specific time period
if it will mature or reprice within that time period. The interest rate
sensitivity gap is defined as the difference between the amount of
interest-earning assets maturing or repricing within a specific time period and
the amount of interest-bearing liabilities maturing or repricing within that
time period. A gap is considered positive when the amount of interest rate
sensitive assets exceeds the amount of interest rate sensitive liabilities. A
gap is considered negative when the amount of interest rate sensitive
liabilities exceeds the amount of interest rate sensitive assets. During a
period of rising interest rates, a negative gap would tend to adversely affect
net interest income while a positive gap would tend to result in an increase in
net interest income. During a period of falling interest rates, a negative gap
would tend to result in an increase in net interest income while a positive gap
would tend to adversely affect net interest income.

         The asset/liability committee, which consists of the chief executive
officer, president and four other directors are charged with monitoring the
liquidity and funds position of Cornerstone. The committee regularly reviews
(a) the rate sensitivity position on a three-month, six-month, and one-year
time horizon; (b) loans to deposit ratios; and (c) average maturity for certain
categories of liabilities.

         Cornerstone operates an internal asset/liability management model. No
estimates of the impact of changing interest rates on historical or projected
earnings are available. The current level of interest rate risk can, however,
be inferred from maturity and repricing data. At March 31, 1997, Cornerstone
had a positive cumulative repricing gap within one year of approximately $4.3
million, or approximately 11.84% of total assets. This positive repricing gap
indicates that Cornerstone's future earnings may be adversely impacted by a
fall in market interest rates. Such an impact would primarily be felt in the
twelve-month period after a fall in rates.

         The following tables represent an interest sensitivity profile for
Cornerstone as of March 31, 1997 and December 31, 1996. The tables represent a
static point in time and do not consider other variables, such as changing
spread relationships or interest rate levels. "Net repricing gap" is the
difference between total earning assets and total interest bearing liabilities
repricing in any given period and "cumulative gap" is the sum of the net
repricing gap from period to period. Interest-bearing demand, savings and money
market account deposits are presented as repricing in the earliest period
presented.

Management has made the following assumptions in the above analysis: (i) Assets
and liabilities are generally assigned to a period based upon their earliest
repricing period when the repricing is less than the contractual maturity; (ii)
Investment securities available for sale are currently treated in the same
manner as comparable securities in the investment securities held to maturity
portfolio in that they are scheduled according to the earlier of their
contractual maturities or earliest repricing dates; and (iii) Interest-bearing
demand deposits, money market deposits and savings deposits that have no
contractual maturities are scheduled in the within 3 months category.

DEPOSITS

         Cornerstone's primary sources of funds are interest bearing deposits.

INVESTMENT POLICY

         The objective of Cornerstone's investment policy is to invest funds
not otherwise needed to meet the loan demand of Cornerstone's market area to
earn the maximum return for Cornerstone, yet still maintain sufficient
liquidity to meet fluctuations in Cornerstone's loan demand and deposit
structure. In doing so, Cornerstone balances the market and credit risks
against the potential investment return, makes investments compatible with the
pledge requirements of Cornerstone's deposits of public funds, maintains
compliance with regulatory investment requirements, and assists the various
public entities with their financing needs. The president is authorized to
execute security transactions for the investment portfolio based on the
decisions of the asset/liability committee. All the investment transactions
occurring since the previous board of directors' meeting are reviewed by the
board at its next monthly meeting, in addition to the entire portfolio. The
investment policy allows portfolio holdings to include short-term securities
purchased to provide Cornerstone's needed liquidity and longer term securities
purchased to generate stable income for Cornerstone during periods of interest
rate fluctuations.

LOAN POLICY                                                       

         All lending activities of Cornerstone are under the direct supervision
and control of the senior loan committee, which consists of the chief executive
officer, president, executive vice president and four other directors. The loan
committee enforces loan authorizations for each officer, decides on loans
exceeding such limits, services all requests for officer credits to the extent
allowable under current laws and regulations, administers all problem credits,
and determines the allocation of funds for each lending division. Cornerstone's
established maximum loan volume to deposits is 85%. The loan portfolio consists
primarily of real estate, commercial and installment loans. Commercial loans
consist of either real estate loans or term loans. Maturity of term loans is
normally limited to five to seven years. Conventional real estate loans may be
made up to 95% of the appraised value or purchase cost of the real estate for
no more than a thirty-year term. Installment loans are based on the earning
capacity and vocational stability of the borrower.

         Management of Cornerstone periodically reviews the loan portfolio,
particularly nonaccrual and renegotiated loans. The review may result in a
determination that a loan should be placed on a nonaccrual status for income
recognition. In addition, to the extent that management identifies potential
losses in the loan portfolio, it reduces the book value of such loans, through
charge-offs, to their estimated collectible value. Cornerstone's policy is to
classify as nonaccrual any loan on which payment of principal or interest is 90
days or more past due except where there is adequate collateral to cover
principal and accrued interest and the loan is in the process of collection. No
concessions are granted and late fees are collected. In addition, a loan will
be classified as nonaccrual if, in the opinion of the management, based upon a
review of the borrower's or guarantor's financial condition, collateral value
or other factors, payment is questionable, even though payments are not 90 days
or more past due.

         When a loan is classified as nonaccrual, any unpaid interest is
reversed against current income. Interest is included in income thereafter only
to the extent received in cash. The loan remains in a nonaccrual classification
until such time as the loan is brought current, when it may be returned to
accrual classification. When principal or interest on a nonaccrual loan is
brought current, if in management's opinion future payments are questionable,
the loan would remain classified as nonaccrual. After a nonaccrual or
renegotiated loan is charged off, any subsequent payments of either interest or
principal are applied first to any remaining balance outstanding, then to
recoveries and lastly to income.

         The large number of consumer installment loans and the relatively
small dollar amount of each makes an individual review impracticable. It is
Cornerstone's policy to charge off any consumer installment loan which is past
due 90 days or more.

         In addition, mortgage loans secured by real estate are placed on
nonaccrual status when the mortgagor is in bankruptcy, or foreclosure
proceedings are instituted. Any accrued interest receivable remains in interest
income as an obligation of the borrower.

         Cornerstone's underwriting guidelines are applied to three major
categories of loans, commercial and industrial, real estate, which includes
residential, construction and development and certain other real estate loans
and consumer loans. Cornerstone requires its loan officers and loan committee
to consider the borrower's character, the borrower's financial condition as
reflected in current financial statements, the borrower's management
capability, the borrower's industry and the economic environment in which the
loan will be repaid. Before approving a loan, the loan officer or committee
must determine that the borrower is basically honest and creditworthy,
determine that the borrower is a capable manager, understand the specific
purpose of the loan, understand the source and plan of repayment, determine
that the purpose, plan and source of repayment as well as collateral are
acceptable, reasonable and practical given the normal framework within which
the borrower operates.

CREDIT RISK MANAGEMENT AND RESERVE FOR LOAN LOSSES

         Credit risk and exposure to loss are inherent parts of the banking
business. Management seeks to manage and minimize these risks through its loan
and investment policies and loan review procedures. Management establishes and
continually reviews lending and investment criteria and approval procedures
that it believes reflect the risk sensitive nature of Cornerstone. The loan
review procedures are set to monitor adherence to the established criteria and
to ensure that on a continuing basis such standards are enforced and
maintained.

         Management's objective in establishing lending and investment
standards is to manage the risk of loss and provide for income generation
through pricing policies. To effectuate this policy, Cornerstone makes
commercial real estate and other loans with one year or less fixed maturity.

         The loan portfolio is regularly reviewed and management determines the
amount of loans to be charged-off. In addition, such factors as Cornerstone's
previous loan loss experience, prevailing and anticipated economic conditions,
industry concentrations and the overall quality of the loan portfolio are
considered. While management uses available information to recognize losses on
loans and real estate owned, future additions to the allowance may be necessary
based on changes in economic conditions. In addition, various regulatory
agencies, as an integral part of their examination process, periodically review
the allowances for losses on loans and real estate owned. Such agencies may
require Cornerstone to recognize additions to the allowances based on their
judgments about information available at the time of their examinations. In
addition, any loan or portion thereof which is classified as a "loss" by
regulatory examiners is charged-off.

         The reserve for loan losses is increased by provisions charged to
operating expense. The reserve is reduced by charging off loans or portions of
loans at the time they are deemed by management to be uncollectible and
increased when loans previously charged off are recovered. The resulting
reserve for loan losses is viewed by management as a single, unallocated
reserve available for all loans and, in management's opinion, is adequate to
provide for reasonably foreseeable potential loan losses. Rules and formulas
relative to the adequacy of the reserve, although useful as guidelines to
management, are not rigidly applied. The reserve for loan losses was $201,000
at year end, or 1.25% of loans outstanding. The following table presents data
related to Cornerstone's reserve for loan losses for the three months ended
March 31, 1997 and the year ended December 31, 1996.

CAPITAL RESOURCES/LIQUIDITY



                                     - 63 -


<PAGE>   77



         Liquidity. Of primary importance to depositors, creditors and
regulators is the ability to have readily available funds sufficient to repay
fully maturing liabilities. Cornerstone's liquidity, represented by cash and
cash due from banks, is a result of its operating, investing and financing
activities. In order to insure funds are available at all times, Cornerstone
devotes resources to projecting on a monthly basis the amount of funds which
will be required and maintains relationships with a diversified customer base
so funds are accessible. Liquidity requirements can also be met through
short-term borrowings or the disposition of short-term assets which are
generally matched to correspond to the maturity of liabilities.

         Although Cornerstone has no formal liquidity policy, in the opinion of
management, its liquidity levels are considered adequate. Cornerstone is not
subject to any specific regulatory liquidity requirements imposed by regulatory
orders. Cornerstone is subject to general FDIC guidelines which do not require
a minimum level of liquidity. Management believes its liquidity ratios meet or
exceed these guidelines. Management does not know of any trends or demands
which are reasonably likely to result in liquidity increasing or decreasing in
any material manner.

         The following table sets forth liquidity ratios for the periods
indicated:

         Impact of Inflation and Changing Prices. The financial statements and
related financial data presented herein have been prepared in accordance with
generally accepted accounting principles which require the measurement of
financial position and operating results in terms of historical dollars without
considering the changes in the relative purchasing power of money over time and
due to inflation. The impact of inflation on operations of Cornerstone is
reflected in increased operating costs. Unlike most industrial companies,
virtually all of the assets and liabilities of Cornerstone are monetary in
nature. As a result, interest rates may have a more significant impact on
Cornerstone's performance than the effects of general levels of inflation.
Interest rates do not necessarily move in the same direction or in the same
magnitude as the price of goods and services.

CAPITAL ADEQUACY

         Capital adequacy refers to the level of capital required to sustain
asset growth over time and to absorb losses. The objective of Cornerstone's
management is to maintain a level of capitalization that is sufficient to take
advantage of profitable growth opportunities while meeting regulatory
requirements. This is achieved by improving profitability through effectively
allocating resources to more profitable businesses, improving asset quality,
strengthening service quality, and streamlining costs. The primary measures
used by management to monitor the results of these efforts are the ratios of
average equity to average assets, average tangible equity to average tangible
assets, and average equity to net loans.

         The FDIC has adopted capital guidelines governing the activities of
banks. These guidelines require the maintenance of an amount of capital based
on risk-adjusted assets so that categories of assets with potentially higher
credit risk will require more capital backing than assets with lower risk. In
addition, banks are required to maintain capital to support, on a risk-adjusted
basis, certain off-balance sheet activities such as loan commitments.

         The capital guidelines classify capital into two tiers, referred to as
Tier I and Tier II. Under risk-based capital requirements, total capital
consists of Tier I capital which is generally common shareholders' equity less
goodwill and Tier II capital which is primarily a portion of the allowance for
loan losses and certain qualifying debt instruments. In determining risk-based
capital requirements, assets are assigned risk-weights of 0% to 100%, depending
primarily on the regulatory assigned levels of credit risk associated with such
assets. Off-balance sheet items are considered in the calculation of
risk-adjusted assets through conversion factors established by the regulators.



                                     - 64 -


<PAGE>   78

The framework for calculating risk-based capital requires banks to meet the
regulatory minimums of 4% Tier I and 8% total risk-based capital.

         In 1990 regulators added a leverage computation to the capital
requirements, comparing Tier I capital to total average assets less goodwill.

         The Federal Deposit Insurance Corporation Improvement Act of 1991
("FDICIA") established five capital categories for banks. Under the regulations

five categories based on its level of risk-based capital as measured by Tier I
capital, total risk-based capital, and Tier I leverage ratios and its
supervisory ratings.

collections, notary public services, escrow service and other customary bank
services to its customers.

EMPLOYEES

         As of March 31, 1997, Cornerstone had approximately 14 full-time
employees. The employees are not represented by a collective bargaining unit.
Cornerstone believes its relationship with its employees to be good.

CUSTOMERS

         It is the opinion of management that there is no single customer or
affiliated group of customers whose deposits, if withdrawn, would have a
materially adverse effect on the business of Cornerstone.

PROPERTIES

         Cornerstone has its principal offices in its main office building at
5319 Highway 153, Chattanooga, Tennessee, which is owned and occupied by
Cornerstone.

LEGAL PROCEEDINGS

         The nature of its business generates a certain amount of litigation
against Cornerstone involving matters arising in the ordinary course of
business. None of the legal proceedings currently pending or threatened to
which Cornerstone is a party or to which any of their properties are subject
will have, in the opinion of management of Cornerstone, a material effect on
the business or financial condition of Cornerstone.

COMPETITION

         All phases of Cornerstone's banking activities are highly competitive.
Cornerstone competes actively with nine commercial banks, as well as finance
companies, credit unions and other financial institutions located in its
service area, which includes Hamilton County, Tennessee.

SUPERVISION AND REGULATION

         Cornerstone is a member of the FDIC and is subject to examination and
regulation by that authority. Cornerstone is chartered under the banking laws
of the State of Tennessee and is subject to the supervision of, and regular
examination by, the TDFI.

         The Tennessee Reciprocal Banking Act requires the filing of an
application with and the approval of the Tennessee Commissioner of Financial
Institutions to acquire a Tennessee bank or bank holding company.

         Tennessee law was amended in 1990 to permit branch banking in any
county in the state. Prior to the amendment, statewide branching was possible
pursuant to a May 1988 federal court decision.

         In December 1991, a major banking bill entitled the Federal Deposit
Insurance Corporation Improvement Act of 1991 ("FDICIA") was enacted, which
substantially revises the bank regulatory and funding provisions of the Federal
Deposit Insurance Act and makes revisions to several other federal banking
statutes. Among other things, FDICIA requires the federal banking regulators to
take "prompt corrective action" in respect of depository institutions that do
not meet minimum capital requirements. Cornerstone has capital levels well
above the minimum requirements. In addition, an institution that is not well
capitalized is generally prohibited from accepting brokered deposits and
offering interest rates on deposits higher than the prevailing rate in its
market and also may not be able to "pass through" insurance coverage for
certain employee benefit accounts. FDICIA also requires the holding company of
any undercapitalized depository institution to guarantee, in part, certain
aspects of such depository institution's capital plan for such plan to be
acceptable. FDICIA contains numerous other provisions, including new
accounting, audit and reporting requirements, beginning in 1995 termination of
the "too big to fail" doctrine except in special cases, limitations on the
FDIC's payment of deposits at foreign branches, new regulatory standards in
such areas as asset quality, earnings and compensation and revised regulatory
standards for, among other things, powers of state banks, real estate lending
and capital adequacy. FDICIA also requires that a depository institution
provide 90 days prior notice of the closing of any branches. Complete
regulations have not yet been issued under FDICIA.

EFFECT OF GOVERNMENTAL POLICIES

         Cornerstone is affected by the policies of regulatory authorities,
including the Federal Reserve System. An important function of the Federal
Reserve System is to regulate the national money supply. Among the instruments
of monetary policy used by the Federal Reserve are: purchases and sales of U.S.
Government securities in the marketplace; changes in the discount rate, which
is the rate any depository institution must pay to borrow from the Federal
Reserve; and changes in the reserve requirements of depository institutions.
These instruments are effective in influencing economic and monetary growth,
interest rate levels and inflation.

         The monetary policies of the Federal Reserve System and other
governmental policies have had a significant effect on the operating results of
commercial banks in the past and are expected to continue to do so in the
future. Because of changing conditions in the national economy and in the money
market, as well as the result of actions by monetary and fiscal authorities, it
is not possible to predict with certainty future changes in interest rates,
deposit levels, loan demand or the business and earnings of Cornerstone or
whether the changing economic conditions will have a positive or negative
effect on operations and earnings.

         Bills are pending before the United States Congress and the Tennessee
General Assembly which could affect the business of Cornerstone, and there are
indications that other similar bills may be introduced in the future. It cannot
be predicted whether or in what form any of these proposals will be adopted or
the extent to which the business of Cornerstone may be affected thereby.

description of the business experience of the executive officers of Cornerstone:

         EARL A. MARLER, JR., Chairman of the Board and Chief Executive

senior vice president



                                     - 68 -

primarily responsible for the retail operations. He received both a B.S. in
Business Administration and a Masters of Business Administration from the

TRANSACTIONS WITH MANAGEMENT

         Cornerstone has and expects to have in the future banking and other
business transactions in the ordinary course of its banking business with
directors, officers, and 10% beneficial owners of Cornerstone and their
affiliates, including members of their families or corporations, partnerships,
or other organizations in which such officers or directors have a controlling
interest, on substantially the same terms (including price, or interest rates
and collateral) as those prevailing at the time for comparable transactions
with unrelated parties. Any such banking transactions will not involve more
than the normal risk of collectibility nor present other unfavorable features
to Cornerstone.

         THE CORNERSTONE BOARD AND ITS COMMITTEES

   
         Directors are elected annually and each director holds office until
his successor is elected and qualified. Committees of the Board and their

                    DESCRIPTION OF CORNERSTONE CAPITAL STOCK

   
         Cornerstone is authorized by its charter (the "Charter") to issue a
maximum of 2,000,000 shares of common stock, $1.00 par value (the "Cornerstone
Common Stock") of which 590,130 were outstanding at July 25, 1997. The
Charter also authorizes the issuance of a maximum of 2,000,000 shares of
preferred stock (the"Preferred Stock"), of which no shares were outstanding at
March 31, 1997.
    

COMMON STOCK

         The holders of Cornerstone Common Stock are entitled to one vote for
each share held of record on all matters submitted to a vote of shareholders.
Cumulative voting is not allowed. Holders of Cornerstone Common Stock are
entitled to receive ratably such dividends, if any, as may be declared by the
Cornerstone Board out of funds legally available therefore and, in the event of
liquidation, dissolution or winding up of Cornerstone, will be entitled to
share ratably in all assets remaining after payment of liabilities. Holders of
Cornerstone Common Stock have no preemptive rights. Holders of Cornerstone
Common Stock have no right to convert their Common Stock into any other
securities. All outstanding shares of Cornerstone are fully paid and
nonassessable. Cornerstone acts as the transfer agent and registrar for
Cornerstone Common Stock.

         Holders of Cornerstone Common Stock are entitled to receive ratably
such dividends, if any, as may be declared by the Board from funds legally
available whether in cash or stock; provided, however, that the declaration and
payment of dividends by the Cornerstone Board shall be subject to the rules and
regulations of the TDFI and the FDIC governing the amount of dividends which
may be paid to shareholders, the manner in which dividends are paid, and the
methods, if any, by which capital stock and surplus may be retired and reduced.
See "Dividends."

PREFERRED STOCK

         The Preferred Stock may be issued by vote of the Cornerstone Board
without shareholder approval, subject in all respects to approval by the TDFI
under the provisions of T.C.A. ss. 45-2-207. The Preferred Stock may be



                                     - 71-

<PAGE>   85



issued in one or more classes and series, with such designations, full or
limited voting rights (or without voting rights), redemption, conversion, or
sinking fund provisions, dividend rates or provisions, liquidation rights, and
other preferences and limitations as the Cornerstone Board may determine in the
exercise of its business judgment. The Preferred Stock may be issued by the
Cornerstone Board for a variety of reasons. Cornerstone has no present plans to
issue any of its Preferred Stock.

         The Preferred Stock could be issued in public or private transactions
in one or more (isolated or series of) issues. The shares of any issue of
Preferred Stock could be issued with rights, including voting, dividend, and
liquidation features, superior to those of any issue or class of Common Stock,
including the shares of Common Stock subject to the Offering. The issuance of
shares of the Preferred Stock could serve to dilute the voting rights or
ownership percentage of holders of the shares (or any other shares of Common
Stock). The issuance of shares of the Preferred Stock might also serve to deter
or block any attempt to obtain control of Cornerstone, or to facilitate any
such attempt.

WARRANTS

   
         As of July 25, 1997, Cornerstone has Warrants outstanding which are 
exercisable for 590,130 shares of Cornerstone Common Stock. The Warrants may be
exercised in whole or in part for $12 per share if exercised by February 8,
1998 and for $15 per share if exercised by February 8, 2001. The Warrants may
not be separately traded but may be transferred with the Common Stock. In order
to exercise the Warrant, the holder must deliver a notice to Cornerstone of the
holder's intent to exercise the Warrant. The Warrant exercise price and the
number of shares which can be purchased on exercise thereof will be adjusted in
the event of stock dividends, stock splits, combinations or reclassifications
and certain other events that would cause a dilution of the Warrants. The
holders of Warrants are not entitled to any rights of holders of shares of
Common Stock.
    

CONTROL-SHARE ACQUISITION PROVISIONS

         Cornerstone's Charter includes a control-share acquisition provision
where acquirers of control blocks of stock are required to obtain disinterested
shareholder approval or by the affirmative vote of 75% of the Cornerstone Board
in order to vote such shares. The Charter specifically provides that no person
shall make a control-share acquisition by directly or indirectly offering to
acquire, or acquiring the beneficial ownership of more than 10% of any class of
an equity security of Cornerstone. In the event a control-share acquisition is
made in violation of the Charter, all stock beneficially owned by any person in
excess of 10% shall be considered "excess stock" and shall not be counted as
stock entitled to vote and shall not be voted by any person or counted as
voting shares in connection with any matters submitted to the shareholders for
a vote.

         Any person who proposes to make or has made a control-share
acquisition may at the person's election deliver an acquiring person statement
to Cornerstone at Cornerstone's principal office. The acquiring person
statement must set forth all of the following: (i) the identity of the
acquiring person and each other member of any group of which the person is a
part for purposes of determining control shares; (ii) a statement that the
acquiring person statement is given pursuant to Article 11 of the Charter;
(iii) the number of shares of Cornerstone owned, directly or indirectly, by the
acquiring person and each other member of the group; (iv) the range of voting
power under which the control-share acquisition falls or would, if consummated,
fall; (v) if the control-share acquisition has not taken place: (a) a
description in reasonable detail of the terms of the proposed control-share
acquisition; and (b) representations of the acquiring person, together with a
statement, in reasonable detail, of the facts upon which they are based, that
the proposed control-share acquisition, if consummated, will not be contrary to
law and that the acquiring person has the financial capacity to make the
proposed control-share acquisition.

         If the acquiring person so requests at the time of delivery of an
acquiring person statement and gives an undertaking to pay Cornerstone's
expenses of an annual meeting, within 10 days thereafter, the directors of
Cornerstone or others authorized to call such a meeting under Cornerstone's
By-Laws shall call a special meeting of



                                     - 72 -


<PAGE>   86



shareholders of Cornerstone for the purpose of considering the voting rights to
be accorded the shares acquired or to be acquired in the control-share
acquisition. Unless the acquiring person agrees in writing to another date, the
special meeting of shareholders shall be held within 50 days after receipt by
Cornerstone of the request. If the acquiring person so requests in writing at
the time of delivery of the acquiring person statement, the special meeting
must not be held sooner than 30 days after receipt by Cornerstone of the
acquiring person statement. If no request is made, the voting rights to be
accorded the shares acquired in the control-share acquisition shall be
presented to the next special or annual meeting of the shareholders.

         If a special meeting is requested, notice of the special meeting of
shareholders shall be given as promptly as reasonably practicable by
Cornerstone to all shareholders of record as of the record date set for the
meeting, whether or not entitled to vote at the meeting. Notice of the special
or annual shareholder meeting at which the voting rights are to be considered
must include or be accompanied by both of the following: (a) a copy of the
acquiring person statement delivered to Cornerstone pursuant to Article 11 of
the Charter; (b) a statement by the Cornerstone Board, authorized by its
directors, of its position or recommendation, or that it is taking no position
or making no recommendation, with respect to the proposed control-share
acquisition.

         Control shares acquired in a control-share acquisition have voting
rights as were accorded the shares before the control-share acquisition only to
the extent granted by resolution approved by a majority of the shares other
than the interested shares or by the affirmative vote of 75% of Cornerstone
Board excluding any director who is proposing to make a control share
acquisition or who is a member of a group making or proposing to make a control
share acquisition.

         To be approved by the shareholders, the resolution must be approved
by: (a) each class or series entitled to vote separately on the proposal by a
majority of all the votes entitled to be cast by the class or series with the
holders of the outstanding shares of a class or series being entitled to vote
as a separate class; and (b) each class or series entitled to vote separately
on the proposal by a majority of all the votes entitled to be cast by that
group, excluding all interested shares.

INDEMNIFICATION OF DIRECTORS AND OFFICERS

         Cornerstone's Charter and By-Laws provide that it may indemnify
directors and officers who are a party to any litigation or proceeding by
reason of the fact that he is or was a director or officer of Cornerstone. Such
indemnification may include reasonable expenses incurred in connection with the
action, suit or proceeding, civil or criminal, except as may be otherwise
limited by law, including attorneys fees and out-of-pocket costs. Such
indemnification will be in accordance with the provisions of the Tennessee
Banking Act and the Tennessee Business Corporation Act and applicable rules and
regulations of all governmental authorities (including but not limited to the
FDIC, the TDFI, and the Federal Reserve Board) as they may exist from time to
time.

         Cornerstone will indemnify its officers, directors, employees and
agents to the maximum extent permitted by law. Judgments, fines and settlements
incurred by him in connection with any such suit or proceeding, if he acted in
good faith and in a manner reasonably believed to be in or not opposed to the
best interest of the corporation, and, in the case of a derivative action on
behalf of the corporation, that he not be adjudged to be liable for negligence
or misconduct, are covered by the indemnification.

SECURITIES LAW LIMITATIONS

         Insofar as indemnification for liabilities arising under the
Securities Act of 1933, as amended (the "Act"), may be permitted to directors,
officers and controlling persons of Cornerstone, Cornerstone has been advised
that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable.

                 EFFECT OF THE MERGER ON RIGHTS OF SHAREHOLDERS

         East Ridge is a Tennessee corporation subject to the provisions of the
TBCA. Cornerstone is a Tennessee banking corporation subject to the provisions
of the TBA and to the extent provisions of the TBCA are not inconsistent with
those of the TBA, Cornerstone is also subject to the provisions of the TBCA.
After the Merger, shareholders of Cornerstone, whose rights are governed by
Cornerstone's current Charter and Bylaws and by theTBA and the TBCA, as
described above, will become shareholders of New Cornerstone whose rights will
then be governed by the Amended and Restated Charter and Amended and Restated
Bylaws of New Cornerstone and by the TBCA. After the Merger, the rights of
shareholders of East Ridge who become shareholders of New Cornerstone will be
governed by the Amended and Restated Charter and Amended and Restated Bylaws of
New Cornerstone. The following is a summary of the material differences in the
rights of shareholders of East Ridge and Cornerstone and is qualified in its
entirety by reference to the governing law and the current Charters and Bylaws
of each of East Ridge and Cornerstone and the proposed Amended and Restated
Charter ("Proposed Charter") and Amended and Restated Bylaws ("Proposed
Bylaws") of New Cornerstone. Copies of the proposed governing documents are
attached hereto as Appendix "D." Certain topics discussed below are also
subject to federal law and the regulations promulgated thereunder, including
those of the FDIC currently applicable to Cornerstone.

REMOVAL OF DIRECTORS

         East Ridge's, Cornerstone's and the Proposed Bylaws provide that any
director is subject to removal by a majority of the directors for cause or by a
majority of the shareholders without cause.

CONFLICT-OF-INTEREST TRANSACTIONS

         The TBCA generally permits transactions involving East Ridge and an
interested director of East Ridge if (i) the material facts are disclosed and a
majority of disinterested directors or a committee of the East Ridge Board
consents, (ii) the material facts are disclosed and a majority of disinterested
shares entitled to vote thereon consents or (iii) the transaction is fair to
East Ridge. The TBCA prohibits loans to directors by East Ridge unless approved
by a majority vote of disinterested shareholders or the East Ridge Board
determines that the loan benefits East Ridge and either approves the specific
loan or a general plan of loans by East Ridge.

         The TBA has no specific provisions with regard to conflicts of
interests of directors; however the rules and regulations of the FDIC goven
such transactions for directors of insured depository institutions.

MEETINGS OF SHAREHOLDERS

         East Ridge's Bylaws authorize the Chairman of the Board, one-third of
the members of the East Ridge Board or, shareholders owning at least 20% of the
outstanding common stock, to call a special meeting of shareholders for any
purpose. Such a call shall state the purpose or purposes of the proposed
meeting.

         Cornerstone's Bylaws and the Proposed Bylaws authorize the President,
one-third of the members of the Board of Directors or, shareholders owning at
least 20% of the outstanding common stock, to call a special meeting of
shareholders for any purpose. Such a call shall state the purpose or purposes
of the proposed meeting.

REQUIRED VOTE FOR AUTHORIZATION OF CERTAIN ACTIONS

         The TBA provides that the recommendation of the Cornerstone Board and
the approval of a majority of the outstanding shares of Cornerstone entitled to
vote thereon is required to effect a merger or consolidation or to sell, lease
or exchange substantially all of Cornerstone's assets.



                                     - 74 -


<PAGE>   88



         The TBCA provides that the approval of the East Ridge Board and of a
majority of the outstanding shares of East Ridge entitled to vote thereon would
also generally be required to approve a merger or to sell, lease, exchange or
otherwise dispose of substantially all of East Ridge's assets. In accordance
with the TBCA, submission by the East Ridge Board of any such action may be
conditioned on any basis, including without limitation, conditions regarding a
supermajority voting requirement or that no more than a certain number of
shares indicate that they will seek dissenters' rights.

         With respect to a merger, no vote of the shareholders of East Ridge
would be required if East Ridge were the surviving corporation and (i) East
Ridge's Charter would remain unchanged after the merger, subject to certain
exceptions, (ii) each shareholder of East Ridge immediately before the merger
would hold an identical number of shares, with identical rights and
preferences, after the merger, (iii) the number of voting shares outstanding
immediately after the merger plus the number of voting shares issuable as a
result of the merger (either by conversion of securities issued pursuant to the
merger or the exercise of rights and warrants issued pursuant to the merger),
will not exceed by more than 20% the number of voting shares of the surviving
corporation outstanding immediately before the merger; and (iv) the number of
participating shares outstanding immediately after the merger, plus the number
of participating shares issuable as a result of the merger (either by
conversion of securities issued pursuant to the merger or the exercise of
rights and warrants issued pursuant to the merger), will not exceed by more
than 20% the total number of participating shares outstanding immediately
before the merger.

         With respect to a sale, lease, exchange or other disposition of
substantially all the assets of East Ridge, no vote of the shareholders of East
Ridge would be required if such transfer were conducted in the regular course
of business or if such transfer were made to a wholly-owned subsidiary of East
Ridge.

         For a discussion of the Control-Share Acquisition provisions of the
Proposed Charter, See "Description of Cornerstone Capital Stock."

ACTION BY WRITTEN CONSENT

         The TBCA provides that action may be taken without a shareholder
meeting and vote if all shareholders entitled to vote on the action consent to
taking such action without a meeting. Action by written consent of the East
Ridge shareholders or the Cornerstone shareholders is impracticable, and action
by written consent of the shraeholders of New Cornerstone will be
impracticable, given the number of holders of East Ridge Common Stock and
Cornerstone Common Stock.

INSPECTION RIGHTS

         The TBCA contains provisions granting shareholders the right to
inspect certain records of each corporation. East Ridge shareholders are
entitled to inspect and copy, during regular business hours at East Ridge's
principal office, the minutes of shareholder meetings, charter, bylaws, annual
reports, and certain other records of the corporation, provided the shareholder
gives the corporation written notice of his demand at least 5 business days
before the date on which he wishes to inspect and copy the records. In
addition, a shareholder who makes a demand in good faith, for a proper purpose,
and describes with reasonable particularity his purpose and the records he
desires to inspect, and if the records are directly connected with his purpose,
may also, upon 5 days' written notice, inspect and copy: (i) accounting records
of the corporation, (ii) the records of shareholders and excerpts from minutes
of any meeting of the board of directors, (iii) records of any action of a
committee of the board of directors while acting in place of the board of
directors on behalf of the corporation, (iv) minutes of any meeting of the
shareholders, and (v) records of action taken by the shareholders or board of
directors without a meeting.

         The TBA has no such provisions.

<PAGE>   89



AMENDMENT OF CERTIFICATE OF INCORPORATION OR CHARTER AND BYLAWS

         The Charter and Bylaws of East Ridge and the Charter and Bylaws of
Cornerstone and the Proposed Charter and the Proposed Bylaws may all be amended
by the affirmative vote of a majority of the outstanding shares entitled to
vote thereon.

VOLUNTARY DISSOLUTION

         The TBCA provides that East Ridge may be dissolved if the East Ridge
Board proposes dissolution and a majority of the shares of East Ridge entitled
to vote thereon approves. In accordance with the TBCA, the East Ridge Board may
condition its submission of a proposal for dissolution on any basis, including
a greater shareholder vote requirement.

         The TBA and the rules and regulations of the FDIC govern the
dissolution of Cornerstone.

INDEMNIFICATION

         The TBCA provides in certain situations for mandatory and permissive
indemnification of directors and officers. The TBCA provides that statutory
indemnification is not to be deemed exclusive of any other rights to which a
director seeking indemnification may be entitled; provided, however, no
indemnification may be made if a final adjudication adverse to the director or
officer establishes his liability (1) for any breach of loyalty to the
corporation or its shareholders; (2) for acts or omissions not in good faith or
which involve intentional misconduct or a knowing violation of law; or (3) for
unlawful distributions.

         The Bylaws of both East Ridge and Cornerstone and the Proposed Bylaws
provide for indemnification of directors and officers as allowed by the TBCA.

BUSINESS COMBINATION STATUTE

         Tennessee's Business Combination Act provides that a party owning 10%
or more of stock in a "resident domestic corporation" (such party is called an
"interested shareholder") cannot engage in a business combination with the
resident domestic corporation unless the combination (i) takes place at least 5
years after the interested shareholder first acquired 10% or more of the
resident domestic corporation, and (ii) either (A) is approved by at least 2/3
of the non-interested voting shares of the resident domestic corporation or (B)
satisfies certain fairness conditions specified in the Business Combination
Act.

         These provisions apply unless one of two events occurs. A business
combination with an entity can proceed without delay when approved by the
target corporation's board of directors before that entity becomes an
interested shareholder, or the resident corporation may enact a charter
amendment or bylaw to remove itself entirely from the Business Combination Act.
This charter amendment or bylaw must be approved by a majority of the
shareholders who have held shares for more than one year prior to the vote. It
may not take effect for at least 2 years after the vote. East Ridge has not
adopted a charter or bylaw amendment removing East Ridge from coverage under
the Business Combination Act.

         The Business Combination Act further provides an exemption from
liability for officers and directors of resident domestic corporations who do
not approve proposed business combinations or charter amendments and bylaws
removing their corporations from the Business Combination Act's coverage as
long as the officers and directors act in "good faith belief" that the proposed
business combination would adversely affect their corporation's employees,
customers, suppliers, or the communities in which their corporation operates
and such factors are permitted to be considered by the board of directors under
the charter.

         For a discussion of the change of control provisions of the FDIC rules
and regulations with respect to Cornerstone and of the Federal Reserve Board
with respect to East Ridge, see "Business of Cornerstone" and "Business of East
Ridge," respectively.

CONTROL SHARE ACQUISITION ACT

         The Tennessee Control Share Acquisition Act ("TCSAA") strips a
purchaser's shares of voting rights any time an acquisition of shares in a
covered Tennessee corporation brings the purchaser's voting power to 1/5, 1/3
or a majority of all voting power. The purchaser's voting rights can be
established only by a majority vote of the other shareholders. The purchaser
may demand a Annual Meeting of shareholders to conduct such a vote. The
purchaser can demand such a meeting before acquiring a control share only if it
holds at least 10% of outstanding shares and announces a good faith intention
to make the control share acquisition. A target corporation may or may not
redeem the purchaser's shares if the shares are not granted voting rights. The
TBA contains no similar provisions.

         The Proposed Charter includes similar provisions to the TCSAA.

INVESTOR PROTECTION ACT

         Tennessee's Investor Protection Act ("TIPA") applies to tender offers
directed at corporations (called "offeree companies") that have "substantial
assets" in Tennessee and that are either incorporated in or have a principal
office in Tennessee. The TIPA requires an offeror making a tender offer for an
offeree company to file with the Commissioner of Commerce and Insurance (the
"Commissioner") a registration statement. When the offeror intends to gain
control of the offeree company, the registration statement must indicate any
plans the offeror has for the offeree. The Commissioner may require additional
information material to the takeover offer and may call for hearings. The TIPA
does not apply to an offer that the offeree company's board of directors
recommends to shareholders.

         In addition to requiring the offeror to file a registration statement
with the Commissioner, the TIPA requires the offeror and the offeree company to
deliver to the Commissioner all solicitation materials used in connection with
the tender offer. The TIPA prohibits "fraudulent, deceptive, or manipulative
acts or practices" by either side, and gives the Commissioner standing to apply
for equitable relief to the Chancery Court of Davidson County, Tennessee, or to
any other chancery court having jurisdiction whenever it appears to the
Commissioner that the offeror, the offeree company, or any of its respective
affiliates has engaged in or is about to engage in a violation of the TIPA.
Upon proper showing, the Chancery Court may grant injunctive relief. The TIPA
further provides civil and criminal penalties for violations.

         The TBA contains no similar provisions with respect to investor
protection.

AUTHORIZED CORPORATION PROTECTION ACT

         The Tennessee Authorized Corporation Protection Act ("TACPA") is the
vehicle through which the Tennessee statutes attempt to permit the Business
Combination Act and the TCSAA to govern foreign corporations. The TACPA
provides that an authorized corporation can adopt a bylaw or a charter
provision electing to be subject to the operative provisions of the Business
Combination Act and the TCSAA, which then become applicable "to the same extent
as such provisions apply to a resident domestic corporation." Authorized
corporations are those that are required to obtain a Certificate of Authority
from the Tennessee Secretary of State and that satisfy any 2 of certain tests
including having its principal place of business located in Tennessee; having a
significant subsidiary located in Tennessee; having a majority of such
corporation's fixed assets located in Tennessee; having more than 10% of the
beneficial owners of the voting stock or more than 10% of such corporation's
shares of voting stock beneficially owned by residents of Tennessee; employing
more than 250 individuals in Tennessee or having an annual payroll paid to
residents of Tennessee that is in excess of $5,000,000; producing goods and/or
services in Tennessee that result

                                     - 77 -


<PAGE>   91



in annual gross receipts in excess of $10,000,000; or having physical assets
and/or deposits located within Tennessee that exceed $10,000,000 in value.

         The United States Court of Appeals for the Sixth Circuit, however, has
held the TACPA unconstitutional as it applies to target corporations organized
under the laws of states other than Tennessee.

         The TBA contains no similar provisions with respect to authorized
corporation protection.

GREENMAIL ACT

         The Tennessee Greenmail Act ("TGA") applies to any corporation
chartered under the laws of Tennessee which has a class of voting stock
registered or traded on a national securities exchange or registered with the
SEC pursuant to Section 12(g) of the Exchange Act. The TGA provides that it is
unlawful for any corporation or subsidiary to purchase, either directly or
indirectly, any of its shares at a price above the market value, as defined in
the TGA, from any person who holds more than 3% of the class of the securities
purchased if such person has held such shares for less than 2 years, unless
either the purchase is first approved by the affirmative vote of a majority of
the outstanding shares of each class of voting stock issued or the corporation
makes an offer of at least equal value per share to all holders of shares of
such class.

         The TBA contains no similar provisions with respect to greenmail.

DIVIDENDS AND OTHER DISTRIBUTIONS

         Neither East Ridge nor Cornerstone has ever paid any dividends on its
common stock.

         The TBA generally allows dividends to be paid out of surplus of
Cornerstone or out of the net profits of Cornerstone for the current fiscal
year and/or the prior fiscal year. Cornerstone is probhibited by the TDFI from
paying dividends for a period of three years from the date Cornerstone began
its operations. See "Information Concerning Cornerstone -- Supervision and
Regulation."

         The TBCA provides that East Ridge generally may make dividends or
other distributions to its shareholders unless after the distribution either
(i) East Ridge would not be able to pay its debts as they become due in the
usual course of business or (ii) East Ridge's assets would be less than the sum
of its liabilities plus the amount that would be needed to satisfy the
preferential dissolution rights of its preferred stock. There are no shares of
East Ridge preferred stock authorized.

DISSENTERS' RIGHTS

         For a discussion of dissenters' rights under the TBA and the TBCA, see
"The Merger -- Dissenters' Rights" and Appendix C.

                            VALIDITY OF COMMON STOCK

         A legal opinion to the effect that the shares of New Cornerstone
Common Stock when issued in accordance with the Merger Agreement, will be
validly issued, fully paid and nonassessable, has been rendered by Baker,
Donelson, Bearman & Caldwell, a Professional Corporation, Memphis, Tennessee,
counsel to Cornerstone.

after giving effect to certain pro forma adjustments described in the

companies, have been included and are of a normal recurring nature. This
unaudited pro forma data should be read in conjunction with the consolidated

forma data set forth in the following pro forma combined condensed balance
sheet does not reflect, due to immateriality, certain accruals, reserves and
one-time costs that may be required to be made by Cornerstone pursuant to the
Merger Agreement which are described under "Summary -- Equivalent and Pro Forma

                       REPORT OF INDEPENDENT ACCOUNTANTS


Board of Directors and Stockholders
East Ridge Bancshares, Inc. and Subsidiary
East Ridge, Tennessee

We have audited the accompanying consolidated balance sheets of East Ridge
Bancshares, Inc. and subsidiary as of December 31, 1996 and 1995, and the
related consolidated statements of income, stockholders' equity and cash flows
for each of the three years in the period ended December 31, 1996.  These
consolidated financial statements are the responsibility of the company's
management.  Our responsibility is to express an opinion on the consolidated
financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the consolidated financial statements
are free of material misstatement.  An audit includes examining, on a test
basis, evidence supporting the amounts and disclosures in the consolidated
financial statements.  An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation.  We believe that our
audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of East Ridge
Bancshares, Inc. and subsidiary as of December 31, 1996 and 1995, and the
results of their operations and their cash flows for each of the three years in
the period ended December 31, 1996, in conformity with generally accepted
accounting principles.

Our audits were made for the purpose of forming an opinion on the basic
consolidated financial statements taken as a whole.  The accompanying
consolidating information is presented for purposes of additional analysis and
is not a required part of the basic consolidated financial statements.  Such
information has been subjected to the auditing procedures applied in the audits
of the basic consolidated financial statements and, in our opinion, is fairly
stated in all material respects in relation to the basic consolidated financial
statements taken as a whole.

The corporation changed its method of accounting for debt securities during
1994.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The accounting and reporting policies and practices of East Ridge Bancshares,
Inc. and subsidiary conform with generally accepted accounting principles and
general practice within the banking industry.

Descriptions of significant policies and practices are as follows:

DESCRIPTION OF BUSINESS - The corporation is a one-bank holding company
primarily conducting business in Hamilton County in Tennessee and the
surrounding areas through its subsidiary, The Bank of East Ridge.

CASH AND DUE FROM BANKS - The company maintains at various financial
institutions cash accounts which may exceed federally insured amounts at times.

CASH AND CASH EQUIVALENTS - For purposes of cash flows, the corporation
considers Federal Funds Sold and other cash items to be cash equivalents.

PRINCIPLES OF CONSOLIDATION - The consolidated financial statements include the
accounts of the parent company and its wholly-owned subsidiary.  All
intercompany accounts and transactions have been eliminated in consolidation.

INVESTMENT SECURITIES - Investment securities that the corporation has the
positive intent and ability to hold to maturity are classified as
held-to-maturity and are stated at cost adjusted for amortization of premiums
and accretion of discounts, which are recognized as adjustments to interest
income.  Investment securities considered available-for-sale are adjusted for
unrealized holding gains and losses and recorded at fair value.  The difference
in fair value and cost adjusted for amortization and accretion for securities
available-for-sale is shown as a separate component of stockholders' equity net
of income tax effects.  Gains or losses on disposition are based on the net
proceeds and the adjusted carrying amount of the securities sold, using the
specific identification method.

ALLOWANCE FOR LOAN LOSSES - The allowance for loan losses is established
through a provision for loan losses charged to expenses.  Loans are charged
against the allowance for loan losses when management believes the collection
of principal is unlikely.  The allowance is determined by management based on
loan loss experience and evaluation of potential loss in the current loan
portfolio.

BANK PREMISES AND EQUIPMENT - Bank premises and equipment are stated at cost
less accumulated depreciation.  Expenditures for repairs and maintenance are
charged to expense as incurred and additions and improvements that
significantly extend the lives of assets are capitalized.  As assets are
retired or otherwise disposed of, cost and accumulated depreciation are removed
from the related accounts and any gain or loss is reflected in operations.

Depreciation is provided primarily using the straight-line method over the
estimated useful lives of the depreciable assets.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - continued

INTEREST INCOME ON LOANS - Interest on loans is accrued and credited to income
based on the principal amount outstanding.  The accrual of interest on loans is
discounted when, in the opinion of management, there is an indication that the
borrower may be unable to meet payments as they become due.  Upon such
discontinuance, all unpaid accrued interest is reversed.

INCOME TAXES - The parent and its wholly-owned subsidiary file consolidated
federal income tax returns.

Income taxes are computed based on the provisions of Statement of Financial
Accounting Standards No. 109, "Accounting for Income Taxes."  Deferred tax
assets and liabilities are recognized for the estimated future tax effects
attributed to temporary differences between book and tax bases of assets and
liabilities and for carryforward items.  The measurement of current and
deferred tax assets and liabilities is based on enacted tax law.  Deferred tax
assets are reduced, if necessary, by a valuation allowance for the amount of
tax benefits that may not be realized.

COMMON STOCK DATA - Earnings per share is computed by dividing the net income
for the period by the weighted average number of common and common equivalent
shares outstanding during the period.

ESTIMATES AND UNCERTAINTIES - The preparation of financial statements in
conformity with generally accepted accounting principles requires management to
make estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period.  Actual results could differ from those estimates.

RECLASSIFICATIONS - Certain reclassifications have been made to prior years'
financial statements to conform with the current year presentation.


INVESTMENT SECURITIES

During 1994, the bank adopted Statement of Financial Accounting Standards No.
115, "Accounting for Certain Investments in Debt and Equity Securities."  The
statement requires investment securities to be classified in three categories:
held-to-maturity, available-for-sale and trading.  For securities to be
classified as held-to-maturity, the bank must demonstrate the positive intent
and ability to hold the securities to maturity.  Trading securities, of which
the bank has none, are securities bought and held principally for the purpose
of selling them in the near future.  Available-for-sale securities are those
securities not classified as held-to-maturity or trading.

The amortized cost and estimated market value of securities at December 31,
1996 and 1995, by contractual maturity, are shown below.  Expected maturities
will differ from contractual maturities because borrowers may have the right to
call or prepay obligations with or without call or prepayment penalties.
Included in U.S. Government Agencies and other securities are certain
collateralized mortgage obligations with an amortized cost of $144,048
available-for-sale and $159,213 held-to-maturity for 1996 and $727,708
available-for-sale and $313,624 held-to-maturity for 1995 and an estimated
market value of $144,487 available-for-sale and $154,337 held-to-maturity for
1996 and $721,696 available-for-sale and $305,394 held-to-maturity for 1995.

amount of $9,450.  Interest will be paid at a rate of 6% per annum with the
note due June 30, 1997.

FINANCIAL INSTRUMENTS WITH OFF-BALANCE-SHEET RISK AND CONCENTRATIONS
OF CREDIT RISK

The bank is a party to financial instruments with off-balance-sheet risk in the
normal course of business to meet the financing needs of its customers.  These
financial instruments include commitments to extend credit and standby letters
of credit.  Those instruments involve, to varying degrees, elements of credit
risk in excess of the amount recognized in the balance sheet.  The contract or
notional amounts of those instruments express the extent of involvement the
bank has in particular classes of financial instruments.

East Ridge Bancshares, Inc. and subsidiary's exposure to credit loss from
nonperformance by the other party to the financial instruments for commitments
to extend credit and standby letters of credit is represented by the
contractual amount of those instruments.  The bank uses the same credit
policies in making commitments and conditional obligations as it does for
on-balance-sheet instruments.

The bank generally requires collateral or other security to support financial
instruments with off-balance-sheet credit risk.

Commitments to extend credit are agreements to lend to customers.  Commitments
generally have fixed expiration dates or other termination clauses and may
require payment of fees.  Since many of the commitments are expected to expire
without being drawn upon, the total commitment amounts do not necessarily
represent future liquidity requirements.  The amount drawn on the total
commitments is $3,475,990 as of December 31, 1996, and $3,805,750 as of
December 31, 1995.  The bank evaluates each customer's credit worthiness on a
case-by-case basis.  The amount of collateral obtained if deemed necessary by
the bank on extension of credit is based on management's credit assessment of
the counterparty.  Collateral held varies but may include certificates of
deposit, assignment of life insurance policies, automobiles and real estate.
The amount collateralized as of December 31, 1996, was 69% and as of December
31, 1995, was 60%.

Standby letters of credit are conditional commitments issued by the bank
guaranteeing performance by a customer to a third party.  The credit risk
involved in issuing letters of credit is essentially the same as that involved
in extending loan facilities to customers.  The bank holds personal guarantees
as collateral supporting those commitments.  The extent of collateral held for
those commitments varies.

FINANCIAL INSTRUMENTS WITH OFF-BALANCE-SHEET RISK AND CONCENTRATIONS OF CREDIT
RISK - continued

The bank's loan portfolio is diversified with regard to customers, industries
and types of collateral although most of the bank's business is in Hamilton
County and 66% of its 1996 loans and 65% of its 1995 loans are real estate
related.  Occasionally, loans to a customer or to a group of related entities
may constitute a concentration of credit risk.  As of December 31, 1996, three
such concentrations existed consisting of loans to three customers representing
17%, 17% and 16% of the bank's total capital.  As of December 31, 1995, four
such concentrations existed consisting of loans to four customers representing
17%, 16%, 16% and 15% of the bank's total capital.

The bank's aggregate amount of cash value life insurance policies as a percent
of the bank's total capital was 22% as of December 31, 1996, and 24% as of
December 31, 1995.

REGULATORY MATTERS

The corporation and bank are subject to various regulatory capital requirements
administered by the federal banking agencies. Failure to meet minimum capital
requirements can initiate certain mandatory - and possibly additional
discretionary - actions by regulators that, if undertaken, could have a direct
material effect on the corporation's financial statements.  Under capital
adequacy guidelines and the regulatory framework for prompt corrective action,
the corporation and bank must meet specific capital guidelines that involve
quantitative measures of the corporation and bank's assets, liabilities, and
certain off-balance-sheet items as calculated under regulatory accounting
practices.  The corporation and bank's capital amounts and classification are
also subject to qualitative judgments by the regulators about components, risk
weightings and other factors.

REGULATORY MATTERS - continued

Quantitative measures established by regulation to ensure capital adequacy
require the corporation and bank to maintain minimum amounts and ratios (set
forth in the table below) of total and Tier I capital (as defined in the
regulations) to risk-weighted assets (as defined), and Tier I capital (as
defined) to average assets (as defined).  Management believes, as of December
31, 1996, that the corporation and bank meet all capital adequacy requirements
to which they are subject.

As of December 31, 1996, the most recent notifications from the Federal Deposit
Insurance Corporation categorized the bank as well capitalized under the
regulatory framework for prompt corrective action.  To be categorized as well
capitalized, the corporation and bank must maintain minimum total risk-based,
Tier I risk-based and Tier I leverage ratios as set forth in the table.  There
are no conditions or events since that notification that management believes
have changed the corporation and bank's category.

The corporation's and bank's actual capital amounts and ratios are also
presented in the table.

             Report of Independent Certified Public Accountants
                         on the Financial Statements




To the Stockholders and Board of Directors
Cornerstone Community Bank
Chattanooga, Tennessee

     We have audited the accompanying balance sheet of Cornerstone Community
Bank as of December 31, 1996, and the related statements of operations, changes
in stockholders' equity, and cash flows from inception (January 23, 1996)
through December 31, 1996.  These financial statements are the responsibility
of the Bank's management.  Our responsibility is to express an opinion on these
financial statements based on our audit.

     We conducted our audit in accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement.  An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements.  An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation.  We believe that our audit provides a reasonable basis
for our opinion.

     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Cornerstone Community Bank
as of December 31, 1996, and the results of its operations and its cash flows
for the period from inception (January 23, 1996) through December 31, 1996, in
conformity with generally accepted accounting principles.

         Bank (Bank) conform with generally accepted accounting principles and
         practices within the banking industry.  The policies that materially
         affect financial position and results of operations are summarized as
         follows:

         Nature of operations:

         The Bank was incorporated under the laws of the state of
         Tennessee on January 23, 1996, and began operations on February 20,
         1996, at its office located in Hixson, Tennessee.  The Bank's primary
         deposit products are demand deposits, savings accounts, and
         certificates of deposit.  Its primary lending products are commercial
         business loans, real estate loans, and installment loans.

         Use of estimates:

         The preparation of financial statements in conformity with
         generally accepted accounting principles requires management to make
         estimates and assumptions that affect the reported amounts of assets
         and liabilities and disclosure of contingent assets and liabilities at
         the date of the financial statements and the reported amounts of
         revenues and expenses during the reporting period.  Actual results
         could differ from those estimates.

         A material estimate that is particularly susceptible to
         significant change relates to the determination of the allowance for
         losses on loans.  In connection with the determination of the allowance
         for losses on loans, management obtains independent appraisals for
         significant properties.

         While management uses available information to recognize losses
         on loans, future additions to the allowance may be necessary based on
         changes in local economic conditions.  In addition, regulatory
         agencies, as an integral part of their examination process,
         periodically review the Bank's allowance for losses on loans.  Such
         agencies may require the Bank to recognize additions to the allowance
         based on their judgments about information available to them at the
         time of their examination. Because of these factors, it is reasonably
         possible that the allowance for losses on loans may change materially
         in the near term.

         Cash and cash equivalents:

         For purposes of reporting cash flows, cash and cash equivalents
         include cash on hand, amounts due from banks, interest-bearing deposits
         at other banks, and federal funds sold. 

         Securities held to maturity:

         The Bank has the positive intent and ability to hold to maturity
         or return of principal all securities held to maturity.  Securities
         held to maturity are reported at cost, adjusted for premiums and
         discounts that are recognized in interest income over the period to
         maturity.

Note 1.  Summary of Significant Accounting Policies (continued)

         Securities available for sale:

         Securities available for sale consist of mortgage-backed
         securities not classified as securities held to maturity.  Unrealized
         holding gains and losses, net of tax, on securities available for sale
         are reported as a net amount in a separate component of stockholders'
         equity until realized.  Gains and losses on the sale of securities
         available for sale are determined using the specific-identification
         method.  Premiums and discounts are recognized in interest income over
         the period to maturity.

         Interest income on loans:
   

         Interest on loans is recognized as income over the term of the loans
         based on the principal amount outstanding. The accrual of interest on
         loans is discontinued when a loan is determined to be impaired. A loan
         is impaired when, in the opinion of management, there is an indication
         that the borrower may be unable to meet payments as they become due. At
         December 31, 1996, the Bank had no loans classified as impaired.  The
         interest accrual was not discontinued on any loans during the year 
         ended December 31, 1996.
    

         Fee income on loans:

         Loan origination fees and certain direct origination costs were
         recognized as income and expense at the time the loan was recorded in
         1996. The effect of not capitalizing these was not significant to the
         accompanying financial statements.
         Allowance for loan losses:

         The allowance for loan losses is maintained at a level which, in
         management's judgment, is adequate to absorb credit losses inherent in
         the loan portfolio.  The amount of the allowance is based on
         management's evaluation of the collectibility of the loan portfolio,
         including the nature of the portfolio, credit concentrations, trends in
         historical loss experience, specific impaired loans, and economic
         conditions.  Allowances for impaired loans are generally determined
         based on collateral values or the present value of estimated cash
         flows. The allowance is increased by a provision for loan losses, which
         is charged to expense, and reduced by charge-offs, net of recoveries.

         Bank premises and equipment: 

         Bank premises and equipment are stated at cost, less accumulated
         depreciation.  Depreciation is computed using the straight-line
         depreciation method and accelerated depreciation methods for both
         financial statement purposes and income tax purposes.  Bank premises
         are depreciated over 30 years; and furniture, fixtures and equipment
         are depreciated over 5 to 12 years. 

         Additions and major renewals and betterments are capitalized and
         depreciated over their estimated useful lives.  Repairs, maintenance,
         and minor renewals are charged to operating expense as incurred.  When
         property is replaced or otherwise disposed of, the cost of such assets
         and the related accumulated depreciation are removed from the 
         accounts.  The gain or loss, if any, is recorded in the statement of
         income.
   

         Income taxes:

         Income taxes are computed based on the provisions of Statement of
         Financial Accounting Standards No. 109, "Accounting for Income Taxes." 
         Deferred tax assets and liabilities are recognized for the extimated
         future tax effects attributed to temporary differences between book
         and tax bases of assets and liabilities and for carryforward
         items.  Deferred tax assets and liablities are reflected at currently
         enacted income tax rates applicable to the period in which the
         deferred tax assets or liabilities are expected to be realized or
         settled.  As changes in tax laws or rates are enacted, deferred tax
         assets and liabilities are adjusted through the provision for income
         taxes.
    

Note 2.  Securities

         Securities have been classified in the balance sheet according
         to management's intent as either securities held to maturity or
         securities available for sale.

Note 3.  Loans and Allowance for Loan Losses (continued)

         The Bank's only significant concentration of credit at December
         31, 1996, occurred in real estate loans which totaled approximately
         $11,979,000.  While real estate loans accounted for 74 percent of total
         loans, these loans were primarily residential development and
         construction loans, residential mortgage loans, commercial loans
         secured by commercial properties, and consumer loans.  Substantially
         all real estate loans are secured by properties located in Tennessee.

         In the normal course of business, the Bank makes loans to directors and
         executive officers of the Bank on substantially the same terms,
         including interest rates and collateral, as those prevailing at the
         time for comparable transactions with other borrowers.  Loans to
         directors and executive officers totaled approximately $130,000 at
         December 31, 1996.

   
         At December 31, 1996, there were no loans specifically classified 
         as impaired by management.  The interest accrual was not discontinued 
         on any loans during the year ended December 31, 1996.

                  Income tax benefit                        $(130,601) 
                                                            =========  

</TABLE>

         The income tax benefit is different from the expected tax benefit
         computed by multiplying loss before income tax benefit by the statutory
         federal income tax rates.  The reasons for this difference relate to
         the provision for loan losses, depreciation of bank premises and
         equipment, and organization and start-up costs.

         The Bank realized a net operating loss for tax purposes in 1996
         which can be carried forward and used to offset future taxable income. 
         This net operating loss carryforward will expire in 15 years.

         As of December 31, 1996, deferred tax assets recognized for
         deductible temporary differences totaled $133,201, and deferred tax
         liabilities for taxable temporary differences totaled $2,600.
         A valuation allowance has not been provided to reduce the deferred
         tax asset from the amount of tax benefit management believes
         it will more likely than not realize. Realization of the net operating
         loss carryforwards is not assured; however, management believes the
         Bank has attained sufficient operations to generate future taxable
         income of approximately $350,000 which would result in the
         realization of such net operating loss carryforwards prior to
         expiration in the year 2011.
Note 7.  Employee Benefit Plan

         The Bank has a 401(k) employee benefit plan covering substantially 
         all employees who have completed at least one year of service and met
         minimum age requirements.  The Bank made no contribution to the plan
         in 1996.


Note 8.  Financial Instruments With Off-Balance-Sheet Risk

         The Bank is a party to financial instruments with off-balance-sheet 
         risk in the normal course of business to meet the financing needs of 
         its customers.  These financial instruments include various
         commitments to extend credit and standby letters of credit. 
         These instruments expose the Bank to varying degrees of credit and
         interest rate risk in excess of the amount recognized in the
         accompanying balance sheet.  To manage this risk, the Bank uses the
         same management policies and procedures for financial instruments with
         off-balance-sheet risk as it does for financial instruments whose risk
         is reflected on the balance sheet.

                          CORNERSTONE COMMUNITY BANK

                        NOTES TO FINANCIAL STATEMENTS
                              December 31, 1996

- --------------------------------------------------------------------------------

Note 8.  Financial Instruments With Off-Balance-Sheet Risk (continued)

         The credit risk of all financial instruments varies based on
         many factors, including the value of collateral held and other security
         arrangements.  To mitigate credit risk, the Bank generally determines
         the need for specific covenant, guarantee, and collateral requirements
         on a case-by-case basis, depending on the customer's creditworthiness.
         The amount and type of collateral held to reduce credit risk vary, but
         may include real estate, machinery, equipment, inventory, and accounts
         receivable as well as cash on deposit, stocks, bonds, and other
         marketable securities that are generally held in the Bank's possession.
         This collateral is valued and inspected to ensure both its existence
         and adequacy.  The Bank requests additional collateral when
         appropriate.

         At December 31, 1996, commitments under standby letters of
         credit and undisbursed loan commitments aggregated $4,081,000.  The
         Bank's credit exposure for these financial instruments is represented
         by their contractual amounts.  The Bank does not anticipate any
         material losses as a result of the commitments under standby letters of
         credit and undisbursed loan commitments.


Note 9.  Stock Options and Warrants

         The Bank has a stock option plan under which members of the
         Board of Directors have been granted options to purchase a total of
         145,000 shares of the Bank's common stock.  The option price is $10.00
         per share, and the options expire ten years from the date of grant.

         The Bank also has a stock option plan under which officers and
         employees have been granted options to purchase a total of 5,200 shares
         of the Bank's common stock.  The option price is $10.00 per share, and
         the options expire ten years from the date of grant.

         A stock warrant was issued with each original share of the
         Bank's common stock which entitles each stockholder to purchase an
         additional share of the Bank's common stock at a specified price.  At
         December 31, 1996, warrants for the purchase of 590,130 shares were
         outstanding.  The exercise price is $12.00 per share within two years
         of issuance and $15.00 per share thereafter.  If not exercised, such
         options will expire five years after issuance.

Note 10. Regulatory Matters

         The Bank is subject to various regulatory capital requirements
         administered by the Tennessee Department of Financial Institutions and
         the federal banking agencies.  Failure to meet minimum capital
         requirements can initiate certain mandatory--and possibly additional
         discretionary--actions by regulators that, if undertaken, could have a
         direct material effect on the Bank's financial statements.  Under
         capital adequacy guidelines and the regulatory framework for prompt
         corrective action, the Bank must meet specific capital guidelines that
         involve quantitative measures of the Bank's assets, liabilities, and
         certain off-balance-sheet items as calculated under regulatory
         accounting practices.  The Bank's capital amounts and classification
         are also subject to qualitative judgments by the regulators about
         components, risk weightings, and other factors.

                              December 31, 1996

- --------------------------------------------------------------------------------



Note 10. Regulatory Matters (continued)

         Quantitative measures established by regulation to ensure
         capital adequacy require the Bank to maintain minimum amounts and
         ratios (set forth in the table below) of total and Tier I capital (as
         defined in the regulations) to risk-weighted assets (as defined), and
         of Tier I capital (as defined) to average assets (as defined). 
         Management believes, as of December 31, 1996, that the Bank meets all
         capital adequacy requirements to which it is subject.

         As of December 31, 1996, the most recent notification from the
         Commissioner of the Tennessee Department of Financial Institutions
         categorized the Bank as well capitalized under the regulatory framework
         for prompt corrective action.  There are no conditions or events since
         that notification that management believes have changed the
         institution's prompt corrective action category.

         The Bank's actual capital amounts and ratios are also presented
         in the table.  Dollar amounts are presented in thousands.

</TABLE>


         The Bank received its charter subject to certain financial and
         nonfinancial conditions.  The chartering conditions are as follows:

           -    The Bank cannot pay dividends for the first
                three years of operation.

           -    Any changes in senior level officers and
                directors for the first two years require written
                regulatory approval.

           -    Director's fees are not to be paid until the
                Bank has achieved an annual operating profit.

           -    The Bank must maintain a Tier I capital to
                assets ratio of no less than 8% during the first three
                years of operation.

           -    The Bank must maintain a minimum allowance for
                loan losses ratio of 1.25% during the first three years of
                operation.

         The Bank was in compliance with all of these chartering
         conditions at December 31, 1996.

         and is subject to shareholder approval, discovery, and regulatory
         approval.

                                   THE MERGER

         1.1      The Merger. On the Effective Date (as defined in Article VII),
Cornerstone will merge (the "Merger") with and into Bank of East Ridge, with
Bank of East Ridge being the surviving corporation (the "Surviving
Corporation"), pursuant to the provisions of, and with the effects provided in,
the Tennessee Business Corporation Act and the Tennessee Banking Act. At the
Effective Time (as defined in Article VII), the charter and bylaws of Bank of
East Ridge (as the Surviving Corporation) shall be the charter and bylaws of
Bank of East Ridge in effect immediately prior to the Effective Time. At the
Effective Time the charter and bylaws of ERB shall be amended and restated to
increase authorized shares of ERB common stock to 1,500,000 shares, change the
name of ERB to Cornerstone Bancshares, Inc. and include other provisions as set
forth on EXHIBIT "C". At the Effective Time the charter and bylaws of the Bank
of East Ridge shall be restated and amended to change the name of "Bank of East
Ridge" to "Cornerstone Community Bank" and to include other provisions as set
forth on EXHIBIT "D". At the Effective Time, the directors and officers of
Cornerstone shall be the directors and officers of the Surviving Corporation. At
the Effective Time, the directors and officers of Cornerstone shall also become
the directors and officers of ERB. The Plan of Merger is set forth as EXHIBIT
"E".

         1.2      Conversion of Cornerstone Common Stock and ERB Common Stock.
By virtue of the Merger, automatically and without any action on the part of
the holder thereof, at the Effective Time, all of the Cornerstone Common
Stock issued and outstanding immediately prior to the Effective Time (other
than shares held directly or indirectly by ERB or any subsidiary of ERB, except
in a fiduciary capacity or in satisfaction of a debt previously contracted, and
other than shares held in the treasury of Cornerstone, which shares shall be
canceled, retired and cease to exist by virtue of the Merger and without any
payment made in respect thereof) shall be converted into the right to receive
shares of New ERB Common Stock, as described below:

                  (a)      Shares of Cornerstone Common Stock and Stock Option
                  Plan.

                           (i) Shares of Cornerstone Common Stock. Each share of
                  Cornerstone Common Stock issued and outstanding at the
                  Effective Time shall become and be converted into one share of
                  New ERB Common Stock, and each outstanding warrant to purchase
                  one share of Cornerstone Common Stock at the Effective Time
                  shall become and be converted into one warrant to purchase one
                  share of New ERB Common Stock for $12.00 per share if
                  exercised by February 8, 1998 and for $15.00 per share if
                  exercised by February 8, 2001 (the "Cornerstone Exchange
                  Ratio");

                           (ii) Cornerstone Stock Option Plan. ERB shall adopt a
                  new stock option plan substantially in the form set forth in
                  Exhibit F. The Cornerstone Statutory-Nonstatutory Stock Option
                  Plan (the "Plan") and all options issued under the Plan will
                  be terminated at the Effective Time, and the new ERB stock
                  option plan shall substitute new options for the terminated
                  options in a transaction described in Section 424(a) of the
                  Code. The holders of all outstanding statutory or nonstatutory
                  options issued under the Plan will receive identical statutory
                  or nonstatutory options to purchase shares of ERB Common Stock
                  subject to the same terms and conditions of the outstanding
                  options issued under the Plan in cancellation of their
                  Cornerstone options. All option holders shall receive credit
                  under the vesting schedule with respect to the new ERB options
                  from the date of the grant of the Cornerstone options.

                           (b) Shares of ERB Common Stock. Each shareholder of
                  ERB Common Stock issued and outstanding at the Effective Time
                  shall have the option to elect from the following:

                           (i) exchange all or a designated portion of the
                  shares of ERB Common Stock for shares of New ERB Common Stock
                  based on an exchange ratio ("ERB Exchange Ratio") determined
                  by multiplying the number of shares of ERB Common Stock held
                  by such shareholder for which he or she elects to be

                                       A-4

<PAGE>   150



                  exchanged by $56.1772 and then dividing by $12.00 (the agreed
                  fair market value of Cornerstone Common Stock); or

                           (ii) exchange all or a designated portion of the
                  shares of ERB Common Stock for cash in the amount of $56.1772
                  per share. If an ERB shareholder elects to receive in cash all
                  or a portion of the consideration to which such shareholder is
                  entitled, the amount of cash to be delivered in exchange for
                  each share of ERB Common Stock shall be determined by
                  multiplying the number of shares of ERB Common Stock held by
                  such shareholder for which he or she elects to receive cash by
                  $56.1772 per share; provided, however, the obligation of ERB
                  to redeem ERB Common Stock for cash shall be limited to
                  $4,287,500, in the aggregate. In the event ERB shareholders in
                  the aggregate elect to exchange ERB Common Stock for more than
                  $4,287,500, ERB shall pay cash to shareholders who have
                  elected to exchange their ERB Common Stock for cash on a
                  pro-rata basis with the balance of the consideration due to
                  such ERB shareholders to be in the form of New ERB Common
                  Stock based on a value of $12.00 per share within the
                  limitation set forth above. In no event shall ERB deliver in
                  cash more than $4,287,500. In the event ERB shareholders elect
                  to receive less than $2,900,000, Cornerstone may terminate
                  this Agreement in accordance with the provisions of Section
                  6.2(f).

                  (c) Change In ERB Common Stock Shares. Subsequent to the date
         of this Agreement but prior to the Effective Date, if the outstanding
         shares of ERB Common Stock shall be increased, decreased, changed into
         or exchanged for a different number or class of shares by reason of any
         reclassification, recapitalization, stock split or reverse stock split,
         split-up or if a stock dividend thereon shall be declared with a record
         date within such period, or other like changes in ERB's capitalization
         shall have occurred, the terms and provisions of Sections 1.2(a) and
         1.2(b) shall be adjusted accordingly.

                  (d) Young. Young agrees to exchange at least seventy percent 
         (70%) of all shares of ERB Common Stock held by him for cash in the 
         amount of $56.1772 per share subject to the limitations set forth in
         Section 1.2(b)(ii).

         1.3      No Fractional Shares. Notwithstanding any other provision
hereof, no fractional shares of New ERB Common Stock and no certificates or
scrip therefor, or other evidence of ownership thereof, will be issued in the
Merger; instead, ERB shall pay to each holder of ERB Common Stock exchanged
pursuant to this Agreement who would otherwise be entitled to a fractional share
an amount in cash determined by multiplying such holder's fractional interest by
$12.00 (rounded to the nearest cent).

         1.4      Procedures.

                  (a)      Exchange of Certificates.

                           (i) Exchange of Certificates by Cornerstone
                  Shareholders for ERB Common Stock. Certificates which
                  represent shares of Cornerstone Common Stock that are
                  outstanding at the Effective Time (each, a "Certificate") and
                  are converted into the right to receive shares of New ERB
                  Common Stock and warrants to purchase New ERB Common Stock
                  pursuant to the Merger shall, after the Effective Time, be
                  exchangeable by the holders thereof in the manner provided in
                  the transmittal materials described below for new certificates
                  representing the shares of New ERB Common Stock into which
                  such shares have been converted.

                           (ii) Exchange of Certificates for Cash and/or ERB
                  Common Stock. Certificates which represent shares of ERB
                  Common Stock that are outstanding at the Effective Time (each,
                  a "Certificate") and are exchanged for cash or New ERB Common
                  Stock in accordance with the provisions of Section 1.2 shall,
                  after the Effective Time, be exchanged by the holders thereof
                  in the

                                       A-5

<PAGE>   151

                  manner provided in the transmittal materials described below
                  for cash or new certificates representing shares of New ERB
                  Common Stock.

                  (b)      Surrender of Certificates.

                           (i) Surrender of Cornerstone Common Stock. As
                  promptly as practicable after the Effective Date, ERB shall
                  send to each holder of record of shares of Cornerstone Common
                  Stock outstanding at the Effective Time transmittal materials
                  for use in exchanging the Certificates for certificates for
                  shares and warrants of the New ERB Common Stock into which
                  such shares and warrants of the Cornerstone Common Stock have
                  been converted pursuant to the Merger. Upon surrender of a
                  Certificate, together with a duly executed letter of
                  transmittal and any other required documents, the holder of
                  such Certificate shall be entitled to receive in exchange
                  therefor a certificate and warrant for the number of shares of
                  New ERB Common Stock to which such holder is entitled. If any
                  such delivery is to be made in whole or in part to a person
                  other than the person in whose name a surrendered Certificate
                  is registered, it shall be a condition to such delivery or
                  exchange that the Certificate surrendered shall be properly
                  endorsed or shall be otherwise in proper form for transfer and
                  that the person requesting such delivery or exchange shall
                  have paid any transfer and other taxes required by reason of
                  such delivery or exchange in a name other than that of the
                  registered holder of the Certificate surrendered or shall have
                  established to the reasonable satisfaction of ERB or its agent
                  that such tax either has been paid or is not payable.

                           (ii) Surrender of ERB Common Stock. As promptly as
                  practicable after the Effective Date, ERB shall send to each
                  holder of record of shares of ERB Common Stock outstanding at
                  the Effective Time transmittal materials for use in exchanging
                  the Certificates for (x) certificates representing shares of
                  the New ERB Common Stock for which such shares of the ERB
                  Common Stock have been exchanged pursuant to Section 1.2, or
                  (y) cash, as the case may be. Upon surrender of a Certificate,
                  together with a duly executed letter of transmittal and any
                  other required documents, the holder of such Certificate shall
                  be entitled to receive in exchange therefor a certificate for
                  the number of shares of New ERB Common Stock or cash, as the
                  case may be, to which such holder is entitled. If any such
                  delivery is to be made in whole or in part to a person other
                  than the person in whose name a surrendered Certificate is
                  registered, it shall be a condition to such delivery or
                  exchange that the Certificate surrendered shall be properly
                  endorsed or shall be otherwise in proper form for transfer and
                  that the person requesting such delivery or exchange shall
                  have paid any transfer and other taxes required by reason of
                  such delivery or exchange in a name other than that of the
                  registered holder of the Certificate surrendered or shall have
                  established to the reasonable satisfaction of ERB or its agent
                  that such tax either has been paid or is not payable.
                  Notwithstanding the foregoing, in the event ERB shareholders
                  in the aggregate elect to exchange ERB Common Stock for more
                  than $4,287,500, ERB shall pay cash to shareholders who have
                  elected to exchange their ERB Common Stock for cash on a
                  pro-rata basis to the extent possible within the limitation
                  set forth above. In no event shall ERB deliver in cash more
                  than $4,287,500.

                  (c)      Cornerstone Shareholders: Rights and
         Dividends/Distributions. No holder of Cornerstone Common Stock shall be
         entitled to exercise any rights as a shareholder of ERB until such
         holder shall have properly surrendered its Certificate(s) (together
         with all required documents) as set forth above. No dividend or other
         distribution payable after the Effective Time with respect to the New
         ERB Common Stock shall be paid to the holder of any unsurrendered
         Certificate until the holder thereof properly surrenders such
         Certificate (together with all required documents), at which time such
         holder shall receive all dividends and distributions, without interest
         thereon, previously withheld from such holder pursuant hereto. After
         the Effective Time, there shall be no transfers on the stock transfer
         books of Cornerstone of shares of Cornerstone Common Stock which were
         issued and outstanding at the Effective Time and converted pursuant to
         the provisions of the Merger into the right to receive New ERB Common
         Stock. If after the Effective Time, Certificates are presented for
         transfer to Cornerstone, they shall be cancelled and exchanged for the
         shares of

                                       A-6

<PAGE>   152



         New ERB Common Stock deliverable in respect thereof as determined in
         accordance with the provisions of Section 1.2 and in accordance with
         the procedures set forth in this Section 1.4(c).

                  (d) Cornerstone and Redeeming ERB Shareholders: Rights. After
         the Effective Time, holders of Cornerstone Common Stock shall cease to
         be, and shall have no rights as, shareholders of Cornerstone, other
         than to receive shares of New ERB Common Stock into which such shares
         have been converted or fractional share payments pursuant to this
         Agreement.

         After the Effective Time, holders of ERB Common Stock who choose to
         redeem their shares of ERB Common Stock shall cease to be, and shall
         have no rights as, shareholders of ERB as to the shares of ERB Common
         Stock redeemed, other than to receive (i) shares of New ERB Common
         Stock for which such shares have been exchanged or (ii) cash, as the
         case may be, pursuant to this Agreement.

                  (e) Liability to Former Shareholders. Notwithstanding the
         foregoing, neither ERB nor Cornerstone nor any other person shall be
         liable to any former holder of shares of Cornerstone or ERB Common
         Stock for any amount properly delivered to a public official pursuant
         to applicable abandoned property, escheat or similar laws.

                  (f) Certificate Replacement. In the event any Certificate
         shall have been lost, stolen or destroyed, upon receipt of appropriate
         evidence as to such loss, theft or destruction and to the ownership of
         such Certificate by the person claiming such Certificate to be lost,
         stolen or destroyed and the receipt by ERB of appropriate and customary
         indemnification including, when appropriate, the posting of bond, ERB
         will issue in exchange for such lost, stolen or destroyed certificate
         shares of New ERB Common Stock and the fractional share payment, if
         any, deliverable in respect thereof as determined in accordance with
         Section 1.3 or cash as the case may be.

                                   ARTICLE II

The Board of Directors

Chattanooga, Tennessee  37343

Re: Re: Fairness Opinion Regarding the Proposed Merger involving Cornerstone
Community Bank, East Ridge Bancshares, Inc., The Bank of East Ridge, and David
E. Young

Dear Directors:

         Mercer Capital Management, Inc. ("Mercer Capital") has been retained by
the Board of Directors of Cornerstone Community Bank ("Cornerstone") to issue a
fairness opinion for the proposed merger between Cornerstone and East Ridge
Bancshares, Inc. ("ERB"). The fairness opinion is issued from a financial point
of view from the perspective of Cornerstone shareholders.

         Under the terms of the Agreement and Plan of Merger by and between
Cornerstone Community Bank, East Ridge Bancshares, The Bank of East Ridge and
David E. Young, Individually, dated March 18, 1997, the following will occur
upon consummation of the merger:

- -        Cornerstone will merge into the Bank of East Ridge with the Bank of
         East Ridge as the surviving corporation. At closing, the Bank of East
         Ridge will amend and restate its charter to change its name to
         Cornerstone Community Bank.

- -        ERB will amend its charter to adapt bylaws substantially similar to
         those currently in effect for Cornerstone, increase its authorized
         shares to 1,500,000, reduce the par value from $10.00 per share to
         $1.00 per share, change the name of ERB, and include other provisions
         satisfactory to Cornerstone. The individuals serving on the board of
         directors of Cornerstone prior to the merger will comprise the board of
         directors of ERB and the Bank of East Ridge subsequent to the merger.

                                       B-1

<PAGE>   168




- -        Cornerstone shareholders will receive one share of ERB common stock for
         each share of Cornerstone common stock. In addition, Cornerstone
         shareholders will receive a warrant to purchase additional ERB common
         stock for $12.00 per share if exercised by February 8, 1998 and $15.00
         per share if exercised by February 8, 2001 to replace warrants
         Cornerstone shareholders now hold. It is anticipated that Cornerstone
         shareholders will exercise approximately 180 thousand of such warrants
         at closing to increase ERB's capital by about $2.2 million.

- -        Based upon arm's length negotiations, ERB shareholders will receive a
         total consideration of $6,125,000, payable in cash of $56.18 per
         existing ERB share, or "new" ERB stock based upon the conversion ratio
         of $56.18 divided by $12.00 per each share of existing ERB share. A
         condition of the merger is that ERB shareholders owning at least 76,321
         shares (70%) elect the cash option. If ERB shareholders elect to
         receive cash greater than 70%, then the proceeds will be reduced on a
         pro rata basis with balance payable in the form of new ERB common
         stock. In the event that ERB shareholders elect to receive less than
         70% cash, then Cornerstone may terminate the Agreement.

- -        David E. Young, the Bank of East Ridge's chief executive officer and
         largest shareholder with a 69.8% interest in ERB, has agreed to
         exchange for cash at least 70% of the shares he owns.

- -        David E. Young has also agreed to be bound by a five year non-compete
         for which he will receive consideration of $75,000 annually. In
         addition, change-of-control benefits totaling up to approximately
         $300,000 may be paid to three Bank of East Ridge officers under certain
         conditions.

The proposed purchase price for ERB's common shares is $6,125,000, or 12.6x
ERB's reported 1996 net income and 200% of book value as of December 31, 1996.
Based upon a discount rate of 7%, the present value of the after-tax payments
which will be made to Mr. Young is about $191,000. In addition, employment
agreement payments may be incurred for three officers, if they elect to
terminate their relationship with The Bank of East Ridge within 30 days of the
consummation of the merger. The after-tax liability of the payments approximates
$189,000.

As part of the engagement, a representative of Mercer Capital visited with
Cornerstone and ERB management in Chattanooga, Tennessee. Mercer Capital was not
asked to, and did not recommend the exchange ratio between ERB and Cornerstone
common stocks and did not assist in the merger negotiations. Factors considered
in rendering the opinion include:

         1.       Terms of the Agreement;

         2.       An analysis of the reasonableness of the proposed
                  consideration which will be paid to ERB shareholders;

         3.       An analysis of the estimated pro-forma changes in the combined
                  entities' balance sheet and income statement, book value per
                  share, earnings per share, and dividends per share from the
                  perspective of the Cornerstone shareholders;

         4.       The tax-free nature of the transaction for Cornerstone
                  shareholders; and,

         5.       Consideration of the ability of the merger to advance
                  Cornerstone's business plan;

                                       B-2

Mercer Capital did not compile nor audit Cornerstone's or ERB's financial
statements, nor have we independently verified the information reviewed. We have
relied upon such information as being complete and accurate in all material
respects. We have not made an independent evaluation of the loan portfolio or
the adequacy of the loan loss reserve, nor have we made specific evaluations of
other assets or liabilities of either institution.

Our opinion does not constitute a recommendation to any shareholder as to how
the shareholder should vote on the proposed merger. Mercer Capital has not
expressed an opinion as to the prices at which any security of Cornerstone or
ERB might trade in the future.

Based upon our analysis of the proposed transaction, it is our opinion that the
transaction is fair to Cornerstone's stockholders from a financial point of
view.


                                Sincerely yours,

                                MERCER CAPITAL MANAGEMENT, INC.

                              WEST'S TENNESSEE CODE
                     TITLE 48. CORPORATIONS AND ASSOCIATIONS
              CHAPTER 23. BUSINESS CORPORATIONS--DISSENTERS' RIGHTS
             PART 1--RIGHT TO DISSENT AND OBTAIN PAYMENT FOR SHARES


48-23-101. Definitions. -- As used in this chapter, unless the context otherwise
requires:

       (1) "Beneficial shareholder" means the person who is a beneficial owner
of shares held by a nominee as the record shareholder;

       (2) "Corporation" means the issuer of the shares held by a dissenter
before the corporate action, or the surviving or acquiring corporation by merger
or share exchange of that issuer;

       (3) "Dissenter" means a shareholder who is entitled to dissent from
corporate action under ss. 48-23-102 and who exercises that right when and in
the manner required by part 2 of this chapter;

       (4) "Fair value", with respect to a dissenter's shares, means the value
of the shares immediately before the effectuation of the corporate action to
which the dissenter objects, excluding any appreciation or depreciation in
anticipation of the corporate action;

       (5) "Interest" means interest from the effective date of the corporate
action that gave rise to the shareholder's right to dissent until the date of
payment, at the average auction rate paid on United States treasury bills with a
maturity of six (6) months (or the closest maturity thereto) as of the auction
date for such treasury bills closest to such effective date;

       (6) "Record shareholder" means the person in whose name shares are
registered in the records of a corporation or the beneficial owner of shares to
the extent of the rights granted by a nominee certificate on file with a
corporation; and

       (7) "Shareholder" means the record shareholder or the beneficial
shareholder.

48-23-102. Right to dissent. -- (a) A shareholder is entitled to dissent from,
and obtain payment of the fair value of the shareholder's shares in the event
of, any of the following corporate actions:

       (1) Consummation of a plan of merger to which the corporation is a party:

              (A) If shareholder approval is required for the merger by ss.
       48-21-104 or the charter and the shareholder is entitled to vote on the
       merger; or
              (B) If the corporation is a subsidiary that is merged with its
       parent under ss. 48-21-105;

       (2) Consummation of a plan of share exchange to which the corporation is
a party as the corporation whose shares will be acquired, if the shareholder is
entitled to vote on the plan;

       (3) Consummation of a sale or exchange of all, or substantially all, of
the property of the corporation other than in the usual and regular course of
business, if the shareholder is entitled to vote on the sale or exchange,




                                       C-1

<PAGE>   171


including a sale in dissolution, but not including a sale pursuant to court
Forder or a sale for cash pursuant to a plan by which all or substantially all
of the net proceeds of the sale will be distributed to the shareholders within
one (1) year after the date of sale;

       (4) An amendment of the charter that materially and adversely affects
rights in respect of a dissenter's shares because it:

            (A) Alters or abolishes a preferential right of the shares;
            (B) Creates, alters, or abolishes a right in respect of redemption,
including a provision respecting a sinking fund for the redemption or
repurchase, of the shares;
            (C) Alters or abolishes a preemptive right of the holder of the
shares to acquire shares or other securities;
            (D) Excludes or limits the right of the shares to vote on any
matter, or to cumulate votes, other than a limitation by dilution through
issuance of shares or other securities with similar voting rights; or
            (E) Reduces the number of shares owned by the shareholder to a
fraction of a share, if the fractional share is to be acquired for cash under
ss. 48-16-104; or

       (5) Any corporate action taken pursuant to a shareholder vote to the
extent the charter, bylaws, or a resolution of the board of directors provides
that voting or nonvoting shareholders are entitled to dissent and obtain payment
for their shares.

       (b) A shareholder entitled to dissent and obtain payment for the
shareholder's shares under this chapter may not challenge the corporate action
creating the shareholder's entitlement unless the action is unlawful or
fraudulent with respect to the shareholder or the corporation.

       (c) Notwithstanding the provisions of subsection (a), no shareholder may
dissent as to any shares of a security which, as of the date of the effectuation
of the transaction which would otherwise give rise to dissenters' rights, is
listed on an exchange registered under ss. 6 of the Securities Exchange Act of
1934, as amended, or is a "national market system security," as defined in rules
promulgated pursuant to the Securities Exchange Act of 1934, as amended.

48-23-103. Dissent by nominees and beneficial owners. -- (a) A record
shareholder may assert dissenters' rights as to fewer than all the shares
registered in the record shareholder's name only if the record shareholder
dissents with respect to all shares beneficially owned by any one (1) person and
notifies the corporation in writing of the name and address of each person on
whose behalf the record shareholder asserts dissenters' rights. The rights of a
partial dissenter under this subsection are determined as if the shares as to
which the partial dissenter dissents and the partial dissenter's other shares
were registered in the names of different shareholders.

       (b) A beneficial shareholder may assert dissenters' rights as to shares
of any one (1) or more classes held on the beneficial shareholder's behalf only
if the beneficial shareholder:

       (1) Submits to the corporation the record shareholder's written consent
to the dissent not later than the time the beneficial shareholder asserts
dissenters' rights; and

       (2) Does so with respect to all shares of the same class of which the
person is the beneficial shareholder or over which the person has power to
direct the vote.

may be entitled to assert dissenters' rights under this chapter and be
accompanied by a copy of this chapter.

       (b) If corporate action creating dissenters' rights under ss. 48-23-102
is taken without a vote of shareholders, the corporation shall notify in writing
all shareholders entitled to assert dissenters' rights that the action was taken
and send them the dissenters' notice described in ss. 48-23-203.

       (c) A corporation's failure to give notice pursuant to this section will
not invalidate the corporate action.


48-23-202. Notice of intent to demand payment. -- (a) If proposed corporate

at a shareholders' meeting, a shareholder who wishes to assert dissenters'

      (1) Deliver to the corporation, before the vote is taken, written notice
of the shareholder's intent to demand payment for the shareholder's shares if
the proposed action is effectuated; and

      (2) Not vote the shareholder's shares in favor of the proposed action. No
such written notice of intent to demand payment is required of any shareholder

the corporation shall deliver a written dissenters' notice to all shareholders
who satisfied the requirements of ss. 48-23-202.

      (b) The dissenters' notice must be sent no later than ten (10) days after
the corporate action was authorized by the shareholders or effectuated,

      (2) Inform holders of uncertificated shares to what extent transfer of the
shares will be restricted after the payment demand is received;

      (3) Supply a form for demanding payment that includes the date of the
first announcement to news media or to shareholders of the principal terms of
the proposed corporate action and requires that the person asserting dissenters'
rights certify whether or not the person asserting dissenters' rights acquired
beneficial ownership of the shares before that date;

      (4) Set a date by which the corporation must receive the payment demand,
which date may not be fewer than one (1) nor more than two (2) months after the
date the subsection (a) notice is delivered; and

      (5) Be accompanied by a copy of this chapter if the corporation has not
previously sent a copy of this chapter to the shareholder pursuant to ss.
48-23-201.

48-23-204. Duty to demand payment. -- (a) A shareholder sent a dissenters'
notice described in ss. 48-23-203 must demand payment, certify whether the
shareholder acquired beneficial ownership of the shares before the date required
to be set forth in the dissenters' notice pursuant to ss. 48-23-203(b)(3), and

                                       C-3

<PAGE>   173


accordance with the terms of the notice.

       (b) The shareholder who demands payment and deposits the shareholder's
share certificates under subsection (a) retains all other rights of a
shareholder until these rights are cancelled or modified by the effectuation of
the proposed corporate action.

      (c) A shareholder who does not demand payment or deposit the shareholder's
share certificates where required, each by the date set in the dissenters'
notice, is not entitled to payment for the shareholder's shares under this
chapter.

      (d) A demand for payment filed by a shareholder may not be withdrawn
unless the corporation with which it was filed, or the surviving corporation,
consents thereto.

48-23-205. Share restrictions. -- (a) The corporation may restrict the transfer
of uncertificated shares from the date the demand for their payment is received
until the proposed corporate action is effectuated or the restrictions released
under ss. 48-23-207.

      (b) The person for whom dissenters' rights are asserted as to
uncertificated shares retains all other rights of a shareholder until these
rights are cancelled or modified by the effectuation of the proposed corporate
action.

48-23-206. Payment. -- (a) Except as provided in ss. 48-23-208, as soon as the
proposed corporate action is effectuated, or upon receipt of a payment demand,
whichever is later, the corporation shall pay each dissenter who complied with
ss. 48-23-204 the amount the corporation estimates to be the fair value of each
dissenter's shares, plus accrued interest.

      (b) The payment must be accompanied by:

      (1) The corporation's balance sheet as of the end of a fiscal year ending
not more than sixteen (16) months before the date of payment, an income
statement for that year, a statement of changes in shareholders' equity for that
year, and the latest available interim financial statements, if any;

      (2) A statement of the corporation's estimate of the fair value of the
shares;

      (3) An explanation of how the interest was calculated;

      (4) A statement of the dissenter's right to demand payment under ss.

      (5) A copy of this chapter if the corporation has not previously sent a
copy of this chapter to the shareholder pursuant to ss. 48-23-201 or ss.
48-23-203.

48-23-207. Failure to take action. -- (a) If the corporation does not effectuate
the proposed action that gave rise to the dissenters' rights within two (2)
months after the date set for demanding payment and depositing share
certificates, the corporation shall return the deposited certificates and
release the transfer restrictions imposed on uncertificated shares.

      (b) If, after returning deposited certificates and releasing transfer
restrictions, the corporation effectuates the proposed action, it must send a
new dissenters' notice under ss. 48-23-203 and repeat the payment demand
procedure.

48-23-208. After-acquired shares. -- (a) A corporation may elect to withhold
payment required by ss. 48-23-206 from a dissenter unless the dissenter was the
beneficial owner of the shares before the date set forth in the dissenters'
notice as the date of the first announcement to news media or to shareholders of
the principal terms of the proposed 





                                       C-4

<PAGE>   174

corporate action.

      (b) To the extent the corporation elects to withhold payment under
subsection (a), after effectuating the proposed corporate action, it shall
estimate the fair value of the shares, plus accrued interest, and shall pay this
amount to each dissenter who agrees to accept it in full satisfaction of the
dissenter's demand. The corporation shall send with its offer a statement of its
estimate of the fair value of the shares, an explanation of how the interest was
calculated, and a statement of the dissenter's right to demand payment under ss.
48-23-209.

48-23-209. Procedure if shareholder dissatisfied with payment or offer. -- (a) A
dissenter may notify the corporation in writing of the dissenter's own estimate
of the fair value of the dissenter's shares and amount of interest due, and
demand payment of the dissenter's estimate (less any payment under ss.
48-23-206), or reject the corporation's offer under ss. 48-23-208 and demand
payment of the fair value of the dissenter's shares and interest due, if:

      (1) The dissenter believes that the amount paid under ss. 48-23-206 or
offered under ss. 48-23-208 is less than the fair value of the dissenter's
shares or that the interest due is incorrectly calculated;

      (2) The corporation fails to make payment under ss. 48-23-206 within two
(2) months after the date set for demanding payment; or

      (3) The corporation, having failed to effectuate the proposed action, does
not return the deposited certificates or release the transfer restrictions
imposed on uncertificated shares within two (2) months after the date set for
demanding payment.

      (b) A dissenter waives the dissenter's right to demand payment under this
section unless the dissenter notifies the corporation of the dissenter's demand
in writing under subsection (a) within one (1) month after the corporation made
or offered payment for the dissenter's shares.

                      PART 3--JUDICIAL APPRAISAL OF SHARES


48-23-301. Court action. -- (a) If a demand for payment under ss. 48-23-209
remains unsettled, the corporation shall commence a proceeding within two (2)
months after receiving the payment demand and petition the court to determine
the fair value of the shares and accrued interest. If the corporation does not
commence the proceeding within the two-month period, it shall pay each dissenter
whose demand remains unsettled the amount demanded.

      (b) The corporation shall commence the proceeding in a court of record
having equity jurisdiction in the county where the corporation's principal
office (or, if none in this state, its registered office) is located. If the
corporation is a foreign corporation without a registered office in this state,
it shall commence the proceeding in the county in this state where the
registered office of the domestic corporation merged with or whose shares were
acquired by the foreign corporation was located.

      (c) The corporation shall make all dissenters (whether or not residents of
this state) whose demands remain unsettled, parties to the proceeding as in an
action against their shares and all parties must be served with a copy of the
petition. Nonresidents may be served by registered or certified mail or by
publication as provided by law.

      (d) The jurisdiction of the court in which the proceeding is commenced
under subsection (b) is plenary and exclusive. The court may appoint one (1) or
more persons as appraisers to receive evidence and recommend decision on the
question of fair value. The appraisers have the powers described in the order
appointing them, or in any amendment to it. The dissenters are entitled to the
same discovery rights as parties in other civil proceedings.

      (e) Each dissenter made a party to the proceeding is entitled to judgment:

      (1) For the amount, if any, by which the court finds the fair value of the
dissenter's shares, plus accrued interest, exceeds the amount paid by the
corporation; or

      (2) For the fair value, plus accrued interest, of the dissenter's
after-acquired shares for which the corporation elected to withhold payment
under ss. 48-23-208.

48-23-302. Court costs and counsel fees. -- (a) The court in an appraisal
proceeding commenced under ss. 48-23-301 shall determine all costs of the
proceeding, including the reasonable compensation and expenses of appraisers
appointed by the court. The court shall assess the costs against the
corporation, except that the court may assess costs against all or some of the
dissenters, in amounts the court finds equitable, to the extent the court finds
the dissenters acted arbitrarily, vexatiously, or not in good faith in demanding
payment under ss. 48-23-209.

      (b) The court may also assess the fees and expenses of counsel and experts
for the respective parties, in amounts the court finds equitable against:

      (1) The corporation and in favor of any or all dissenters if the court
finds the corporation did not substantially comply with the requirements of part
2 of this chapter; or

      (2) Either the corporation or a dissenter, in favor of any other party, if
the court finds that the party against whom the fees and expenses are assessed
acted arbitrarily, vexatiously, or not in good faith with respect to the rights
provided by this chapter.

      (c) If the court finds that the services of counsel for any dissenter were
of substantial benefit to other dissenters similarly situated, and that the fees
for those services should not be assessed against the corporation, the court may
award to these counsel reasonable fees to be paid out of the amounts awarded to
the dissenters who were benefited.

                           voting power with respect to shares of the
                           Corporation that, when added to all other shares of
                           the Corporation owned by a person or in respect to
                           which that person may exercise or direct the exercise
                           of voting power, would entitle that person,
                           immediately after acquisition of the shares, directly

                                    is consummated in any of the following
                                    circumstances:

                                             Corporation would have constituted 
                                             a Control-Share Acquisition but for

shall be closed for the purpose of determining shareholders, such books shall be
closed for at least ten days immediately preceding such meeting. In lieu of
closing the stock transfer books, the Board of Directors may fix in advance a
date as the record date for any such determination of shareholders, such date in
any case to be not more than sixty days and, in case of a meeting of
shareholders, not less than ten days prior to the date on which the particular
action requiring such determination of shareholders is to be taken. If the stock

held by each shareholder, which list, for a period of ten days prior to such

business hours. Such list shall be certified by the corporate officer
responsible for its preparation or by the transfer agent and shall be produced
and kept open at the time and place of the meeting and be subject to the
inspection of any shareholder during the entire time of the meeting. In the
event of any challenge to the right of any person to vote at the meeting, the
presiding officer at such meeting may rely on said list as proper evidence of
the right of parties to vote at such meeting.

         Section h.        Quorum. Except as may be otherwise provided by law, a
majority of the outstanding shares of the corporation entitled to vote,
represented in person or by proxy, shall constitute a quorum at a meeting of
shareholders. In the event that a majority of the outstanding shares are
represented at any meeting, a majority of the shares represented thereat
entitled to vote shall decide any question brought before such meeting, unless
the question is one upon which by express provision of law or of the certificate
of incorporation or of these bylaws a larger or different vote is required, in
which case such express provision shall govern and control the decision of each
question.

         Section i.        Proxies. Shareholders of record who are entitled to 
vote may vote at any meeting either in person or by proxy in writing, which
shall be filed with the Secretary of the meeting before being voted. Such proxy

determine and specify, and if so determined no notice thereof need be given,
provided that unless all the directors are present at the meeting at which said
resolution is passed, that the first meeting held pursuant to said resolution
shall not be held for at least two days following the date on which the
resolution is passed.

         Section d.        Special Meetings. Special meetings of the Board of 
Directors may be held at any time or place whenever called by the President, or
by written request of at least one-third of the directors, or any two (2)
executive officers, notice thereof being given to each director by the Secretary
or other officer calling the meeting, or they may be held at any time without
formal notice provided all of the directors are present or those not present
shall at any time waive or have waived notice thereof.

         Section e.        Notice. Notice of any special meetings shall be given
at least twenty-four hours previously thereto by written notice delivered
personally or by telegram or at least five days previously thereto by written
notice mailed to each director at his business address. If mailed, such notice
shall be deemed to be delivered when deposited in the United States mail so
addressed, with postage thereon prepaid. If notice be given by telegram, such
notice shall be deemed to be delivered when the telegram is delivered to the
telegraph company.

         Section f.        Quorum. A majority of the members of the Board of 
Directors as constituted for the time being shall constitute a quorum for the
transaction of business, but a lesser number may adjourn any meeting and the
meeting may be held as adjourned without further notice. When a quorum is
present at any meeting, a majority of the members present thereat shall decide
any question brought before such meeting, except as otherwise provided by law or
by these bylaws. The fact that a director has an interest in a matter to be
voted on at the meeting shall not prevent his being counted for purposes of a
quorum.

         Section g.        Vacancies.  Any vacancy occurring in the Board of 
Directors, including vacancies by virtue of removal for cause, may be filled by
the vote of a majority of the remaining Directors.

         Section h.        Compensation. By resolution of the Board of 
Directors, the directors may be paid their expenses, if any, of attendance at
each meeting of the Board of Directors, and may be paid a fixed sum for
attendance at each meeting of the Board of Directors or a stated salary as a
director. No such payment shall preclude any director from serving the
corporation in any other capacity and receiving compensation therefor.

         Section i.        Removal.  Any director may be removed without cause 
by a majority vote of the shareholders. A director may be removed for cause by a
majority of the entire Board of Directors. Cause shall be defined as the final
conviction of a felony, declaration of unsound mind by court order, adjudication
of bankruptcy, nonacceptance of office or conduct prejudicial to the interest of
the corporation.

         Section j.        Committees. The majority of the Board of Directors 
may appoint an executive committee, loan committee and investment committee or
such other committees as it may deem advisable, composed of two or more
directors, and may delegate authority to such committees as is not inconsistent
with the Tennessee Business Corporation Act. The members of such committee shall
serve at the pleasure of the Board of Directors.

         Section k.        Presumption of Assent. A director of the corporation 
who is present at a meeting of the Board of Directors at which action on any
corporate matter is taken shall be presumed to have assented to the action taken
unless his dissent shall be entered in the minutes of the meeting or unless he
shall file his written dissent to such action with the person acting as the
Secretary of the meeting before the adjournment thereof or shall forward such
dissent by registered mail to the Secretary of the corporation immediately after
the adjournment of the meeting. Such right to dissent shall not apply to a
director who voted in favor of such action.

         Section l.        Informal Action by Directors. Any action required to
be taken at a meeting of the Board of Directors, or any other action which may
be taken at a meeting of the Board of Directors, may be taken without a meeting
if a consent in writing, setting forth the action so taken, shall be signed by
all of the directors entitled to vote with respect to the subject matter
thereof.

         Whenever any notice whatever is required to be given by these bylaws,
or the certificate of incorporation of this corporation, or any other
corporation laws of the State of Tennessee, a waiver thereof in writing signed
by the person or persons entitled to such notice, whether before or after the
time stated therein, shall be deemed equivalent thereto. Where the person or
persons entitled to such notice sign the minutes of any shareholder's or
directors meeting, which minutes contain the statement that said person or
persons have waived notice of the meeting, then such person or persons are
deemed to have waived notice in writing.

each annual meeting of the shareholders. If the election of officers shall not
be held in such meeting, such election shall be held as soon thereafter as
conveniently may be. No officer shall be elected for a term in excess of one (1)
year. Subject to the foregoing, each officer shall hold office until his
successor shall have been duly elected and shall have qualified or until his
death or until he shall resign or shall have been removed in the manner
hereinafter provided.

         Section c.        Removal. Any officer or agent elected or appointed

person so removed.

other duties as may be prescribed by the Board of Directors from time to time.

                     INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20.  Indemnification of Directors and Officers

         Tennessee Code Annotated Sections 48-18-501 through 48-18-509
authorize a corporation to provide for the indemnification of officers,
directors, employees and agents in terms sufficiently broad to permit
indemnification under certain circumstances for liabilities (including
reimbursement for expenses incurred) arising under the Securities Act of 1933,
as amended. East Ridge has adopted the provisions of the Tennessee statute
pursuant to Article XXIV of its Bylaws. 

         Tennessee Code Annotated, Section 48-12-102, permits the inclusion in
the charter of a Tennessee corporation of a provision, with certain exceptions,
eliminating the personal monetary liability of directors to the corporation or
its shareholders for breach of the duty of care. East Ridge has adopted the
provisions of the statute in paragraph Ninth of its charter.

Item 22.  Undertakings

         (a) Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the Registrant pursuant to the foregoing provisions or otherwise,
the Registrant has been advised that in the opinion of the Securities and
Exchange Commission, such indemnification is against public policy as expressed
in the Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant for expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.

         (b) The undersigned Registrant hereby undertakes:

         (1) to file, during any period in which offers or sales of the
securities are being made, a post-effective amendment to this Registration
Statement:

         (i)      to include any Prospectus required by Section 10(a)(3) of the
                  Securities Act of 1933;

         (ii)     to reflect any facts or events arising after the effective
                  date (or most recent post-effective amendment) which,
                  individually, or in the aggregate, represent a fundamental
                  change in the information set forth in the Registration
                  Statement;

         (iii)    to include any material information with respect to the plan
                  of distribution not previously disclosed or any material
                  change to such information set forth in the Registration
                  Statement.

         Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not
         apply if the registration statement is on Form S-3, Form S-8, and the
         information required [or] to be included in a post-effective amendment
         by those paragraphs is contained in periodic reports filed by the
         Registrant pursuant to section 13 or section 15(d) of the Securities
         Exchange Act of 1934 that are incorporated by reference in the
         registration statement.

         (2) that, for the purpose of determining any liability under the
Securities Act of 1933, each post-effective amendment shall be deemed to be a
new Registration Statement relating to the securities offered therein and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

         (3) to remove from registration by means of a post-effective amendment
any of the securities being registered which remain unsold at the termination
of the offering.

         (c) The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to section 13(a) or section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
Registration Statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

         (d) The undersigned Registrant hereby undertakes as follows: that
prior to any public reoffering of the securities registered hereunder through
use of a prospectus which is a part of this Registration Statement, by any
person or party who is deemed to be an underwriter within the meaning of Rule
145(c), the issuer undertakes that such
<PAGE>   190



reoffering prospectus will contain the information called for by the applicable
registration form with respect to reofferings by persons who may be deemed
underwriters, in addition to the information called for by the other Items of
the applicable form.

         (e) The Registrant undertakes that every prospectus (i) that is filed
pursuant to paragraph (d) immediately preceding, or (ii) that purports to meet
the requirements of section 10(a)(3) of the Act and is used in connection with
an offering of securities subject to Rule 415, will be filed as a part of an
amendment to the Registration Statement and will not be used until such
amendment is effective, and that, for purposes of determining any liability
under the Securities Act of 1933, each such post-effective amendment shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

         (f) The undersigned Registrant hereby undertakes to respond to
requests for information that is incorporated by reference into the Proxy
Statement-Prospectus pursuant to Items 4, 10(b), 11, or 13 of this Form, within
one business day of receipt of such request, and to send the incorporated
documents by first class mail or other equally prompt means. This includes
information contained in documents filed subsequent to the effective date of
the Registration Statement through the date of responding to the request.

         (g) The undersigned Registrant hereby undertakes to supply by means of
a post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the Registration Statement when it became effective.
